ACTIVITY. GROUP ACTIVITY: 1. Prepare a ruler, a protractor, a pencil and a bond paper. 2. Work in group of four. 3. Follow the demonstration by the teacher. a. Draw a 7- inch segment. b. Name it BE. c. Using your protractor make angle B equal to 70°. d. From the vertex draw BL measuring 8 inches long. e. How many triangles can be formed? f. Draw ∆BEL g. Compare your triangle with the triangles of the other members of the group. Do you have congruent triangles? h. Lay one triangle on top of the others. Are all the corresponding sides congruent How about the corresponding angles? i. What can you say about any pair of congruent triangles? 4. Reporters will present the answer in front. Minimum of 2 reporters per group..

• Congruence Triangle are defined by six corresponding congruent parts (three corresponding congruent sides and three corresponding congruent interior angles)..

Page 12 (4m 12s)

• Included angle is the angle between two sides of a triangle • Included side is the side common to two angles of a triangle..

Page 13 (4m 33s)

- If the two sides and an included angle of one triangle are congruent to the corresponding two sides and the included angle of another triangle, then the triangles are congruent..
