Semi – Detailed Lesson Plan

I. Objectives

1. Define transversal.2. Identify and name the different angles formed by parallel lines.

.

II. Subject Matter

Topic: Angles Formed by Parallel Lines Cut by a Transversal

References: Geometry by Soledad Jose-Dilao and Julieta Bernabe Discovering Mathematics by De Guzman

Materials: Visual Screen, Whiteboard Marker and board

III. Instructional Procedure

A. Preparation

1. Prayer2. Greetings3. Checking of attendance

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.

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 angles2. pairs of alternate interior angles3. pairs of alternate exterior angles

V. AssignmentIn the given figure, tell whether, it is an exterior angle, interior angle, alternate interior angles, alternate exterior angles and corresponding angles.

Line t is a transversal of lines f and g.

1) angle 1 and angle 72) angle 4 and angle 63) angles 1, 2, 8 and 74) angle 3 and angle 75) angles 1, 2, 8 and 7
