Presented by: JOVANIE O. PANILAG.. TRIANGLE CONGRUENT POSTULATE SAS (side-angle-side) congruent postulate..

OBJECTIVE:. At the end of this lesson, the students will be able to: Illustrate SAS (side-angle-side) congruent postulate (M8GE-IIId-e-1)..

FILL IN THE BLANK!. 1. A_G_E - It is a figure which formed by two rays or a lines that shared a common endpoint. 2. T_I_N_L_ - It is a plane figure with three straight sides and three angles. 3. S_D_S - It is a position to the left or right of an object, place and central point..

FILL IN THE BLANK!. 1. ANGLE - It is a figure which formed by two rays or a lines that shared a common endpoint. 2. TRIANGLE - It is a plane figure with three straight sides and three angles. 3. SIDES - It is a position to the left or right of an object, place and central point..

- What is ASA (angle-side-angle) congruent postulate and how can you illustrate ASA congruent postulate?.

What have you notice about the picture being shown?.

Triangle Congruent Postulate SAS (side-angle-side) congruent postulate..

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..

How did you answer the activity? Did you find hard to answer the activity? What did the activity all about?.

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

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

- 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..

SAS (Side-Angle-Side) Congruence Postulate. If BA ≅ ED, ∠B ≅ ∠E, AC ≅ DF Then ∆BAC ≅ ∆EDF by SAS Congruence Postulate..

1. What is SAS stand for? 2. What is SAS (side-angle-side) congruent postulate? 3. What have you learn about our discussion..

Direction: Complete the congruence statement using SAS (side-angle-side) congruence postulate..

Direction: In a ½ sheet of paper. Complete the congruence statement using SAS (side-angle-side) congruence postulate..

Study and research in advance about SSS (side-side-side) congruent postulate..
