Transversal.lines.3rdyr

  1. 1. 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 JulietaBernabe Discovering Mathematics by De Guzman Materials: Visual Screen, Whiteboard Marker and board III. Instructional Procedure A. Preparation 1. Prayer 2. Greetings 3. 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.
  2. 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 In the given figure, tell whether, it is an exterior angle, interior angle, alternate interior angles, alternate exterior angles and corresponding angles. Line tis a transversal of lines f and g. 1) 2) 3) 4) 5) angle 1 and angle 7 angle 4 and angle 6 angles 1, 2, 8 and 7 angle 3 and angle 7 angles 1, 2, 8 and 7 Prepared by: Allan C.
