B. Review
Last meeting, we discussed about Perpendicular Lines, again what are
Perpendicular Lines?
C. Motivation
Rectangular Solid Figure
D. Presentation
Discuss the topic and present some illustrative examples and activities
that will enhance their learning and knowledge acquisition about the use of
a transversal.
2. E. Applications
Using the figure below:
1. Find the exterior and interior angles.
2. Name the corresponding angles.
3. From the pairs of angles, identify the pairs of alternate interior angles
and pairs of alternate exterior angles.
IV.
Evaluation
In the figure, the transversal is UV and QR I I ST.
Identify the following:
1. exterior angles and interior angles
2. pairs of alternate interior angles
3. pairs of alternate exterior angles
V.
Assignment
