L.E.Q. How do you identify congruent figures and their corresponding parts? The Same Shape and The Same Size. Polygons that have congruent corresponding parts – their matching sides and angles. Always list corresponding vertices in the same order. Sides: Angles: The fins of the space shuttle discovery model congruent pentagons. Find mB . Two triangles are congruent if and only if they have 3 pairs of congruent corresponding sides and 3 pairs of congruent corresponding angles. Decide whether the triangles are congruent. Justify your answer. ◦ 3 Sides: ◦ 3 Angles: If 2 angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. ◦ So based upon the picture, we can conclude that… Use the info in the diagram to prove that PQR PSR. Give a reason why each statement is true. Suppose that 2 pentagons are congruent. How many pairs of congruent corresponding parts are there? Explain. Pgs. 182 – 183 #s 1 – 12, 16 – 28, 30 - 31.
