This Lesson Plan- Mathematics Year 10 (SSS 1) is a one of LeadinGuides free lesson plans for teachers. The lesson plans are ready-made for teachers.  This means teachers can download, print (if necessary) and submit it as is.

A member contributed this lesson plan. As such, despite I noted that this Lesson Plan- Mathematics Year 10 (SSS 1) is ready-made; there are few things users should note.

First, cross-check the content with your curriculum or scheme of work. Make sure that the topics matches the curriculum that your school uses. I checked to confirm that the content corresponds to that of the national curriculum. So, if your school uses the national curriculum; it should match with this plan. If you need our official Schemes of Work based on the latest 9-Year BEC, kindly check our store to download it. Alternatively, click here to have me send them to you on WhatApp.

Also, you should note that lesson plan has different formats. As such, be sure that the format of this lesson plan matches your school’s scheme. Nonetheless, the key components will be the same all through.

Finally, this is a lesson plan. Lesson plans are different from lesson notes. I discussed the differences in another post. Click here to see the differences between lesson plan and lesson note.

Because this is a lesson plan, it provides skeletal outline of how a teacher may present the lesson. Parents that home-school or support their children at home should find it equally useful as our lesson notes.

The teacher introduces the lesson to the students in the following steps:

STEP 1

Do you know real numbers?

When a transversal intersects two or more lines in the same plane, a series of angles are formed. Certain pairs of angles are given specific “names” based upon their locations in relation to the lines. These specific names may be used whether the lines involved are parallel or not parallel.

Names” given to pairs of angles:

·         Alternate interior angles

·         Alternate exterior angles.

·         Corresponding angles.

·         Interior angles on the same side of the transversal.

Alternate Interior Angles:


The word “alternate” means “alternating sides” of the transversal.
This name clearly describes the “location” of these angles.
When the lines are parallel,
the measures are equal.
Alternate interior angles are “interior” (between the parallel lines), and they “alternate” sides of the transversal. Notice that they are not adjacent angles (next to one another sharing a vertex).

When the lines are parallel,
the alternate interior angles
are equal in measure.
m1 = m2 and m3 = m4

∠1 and ∠2 are alternate interior angles
∠3 and ∠4 are alternate interior angles

Lesson Plan- Mathematics Year 10 (SSS 1)- Image of alternate interior anglesn

If two parallel lines are cut by a transversal, the alternate interior angles are congruent.

If two lines are cut by a transversal and the alternate interior angles are congruent, the lines are parallel.

Hint

If you draw a Z on the diagram, the alternate interior angles can be found in the corners of the Z. The Z may also be backward:.

 

 

Alternate Exterior Angles:

The word “alternate” means “alternating sides” of the transversal.
The name clearly describes the “location” of these angles.
When the lines are parallel,
the measures are equal.

Alternate exterior angles are “exterior” (outside the parallel lines), and they “alternate” sides of the transversal. Notice that, like the alternate interior angles, these angles are not adjacent.

 Image of Alternate Exterior Angles

When the lines are parallel, the alternate exterior angles
are equal in measure.
m1 = m2 and m3 = m4

∠1 and ∠2 are alternate exterior angles
∠3 and ∠4 are alternate exterior angles

Exterior Alternate Angles 2

If two parallel lines are cut by a transversal, the alternate exterior angle are congruent.

If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel

 

 

Corresponding Angles:

The name does not clearly describe the “location” of these angles. The angles are on the SAME SIDE of the transversal, one INTERIOR and one EXTERIOR, but not adjacent.
The angles lie on the same side of the transversal in “corresponding” positions.
When the lines are parallel,
the measures are equal.

 

If you copy one of the corresponding angles and you translate it along the transversal, it will coincide with the other corresponding angle. For example, slide ∠ 1 down the transversal and it will coincide with ∠2.

When the lines are parallel,
the corresponding angles
are equal in measure.
m1 = m2 and m3 = m4
m5 = m6 and m7 = m8

Lesson Plan- Mathematics Year 10 (SSS 1)- Image of Corresponding Angles

∠1 and ∠2 are corresponding angles
∠3 and ∠4 are corresponding angles
∠5 and ∠6 are corresponding angles
7 and 8 are corresponding angles

 

If you draw a F on the diagram, the corresponding angles can be found in the corners of the F. The F may also be backward and/or upside-down:   ꟻ   Ⅎ .

Hint

If two parallel lines are cut by a transversal, the corresponding angles are congruent.

Congruent Angles

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

 

 

 

Interior Angles on the Same Side of the Transversal:

The name is a description of the “location” of these angles.
When the lines are parallel,
the measures are supplementary.

These angles are located exactly as their name describes. They are “interior” (between the parallel lines), and they are on the same side of the transversal.

When the lines are parallel,
the interior angles on the same side of the transversal are supplementary.
m1 + m2 = 180
m3 + m4 = 180

∠1 and ∠2 are interior angles on the same side of transversal
∠3 and ∠4 are interior angles on the same side of transversal

Transverse Interior Angles

If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.

If two lines are cut by a transversal and the interior angles on the same side of the transversal are supplementary, the lines are parallel.

 

 

In addition to the 4 pairs of named angles that are used when working with parallel lines (listed above), there are also some pairs of “old friends” that are also working in parallel lines

 

 

Vertical Angles:

When straight lines intersect, vertical angles appear.
Vertical angles are ALWAYS equal in measure,
whether the lines are parallel or not.

 

There are 4 sets of vertical angles in this diagram!

1 and 2
3 and 4
and 6
7 and 8

Remember: the lines need not be parallel to have vertical angles of equal measure.

Theorem: vertical angles are congruent.

Linear Pair Angles:

A linear pair are two adjacent angles forming a straight line.
Angles forming a linear pair are
ALWAYS supplementary.

Since a straight angle contains 180º, the two angles forming a linear pair also contain 180º when their measures are added (making them supplementary).
m∠1 + m∠4 = 180
m∠1 + m∠3 = 180
m∠2 + m∠4 = 180
m∠2 + m∠3 = 180
m∠5 + m∠8 = 180
m∠5 + m∠7 = 180
m∠6 + m∠8 = 180
m∠6 + m∠7 = 180

Theorem: If two angles form a linear pair, they are supplementary
