Question

2. Which pairs of triangles are congruent by ASA congruence condition in Fig. 9.29? If
congruent, write the congruence of the two triangles in symbolic form.​

Answer 1

Answer:

According to ASA

first we will find angle X of Triangle XYX

X + Y + Z = 180°

X + 30° + 90° = 180°

X + 120° = 180°

X = 180° - 120°

X = 60°

Now, we can observe that

angle C = angle X ( both 60° )

angle Z = angle B ( both 90°)

XY = AC

So , hence proved by ASA
