Question

Note: 1. Two congruent triangles have equal areas and equal perimeters.
2. If three angles of a triangle are equal to three angles of the other triangle, then the triangles are n
Example 1: In the given figure, state whether the triangles are congruent or not.
Solution: The given figure has two triangles, AABC and AADC.
necessarily congruent. This is because triangles can have same angles but can be of different size
In AABC and AADC,
AB = AD = 7.8 cm
BC = CD = 3.6 cm
and AC = AC = 5 cm
Therefore, AABC = AADC, by SSS congruence condition.
