Similarity of Triangles

If in two triangles, corresponding angles are equal, then their corresponding sides are

• In the same ratio

• Equal

• None of these

If in two Triangles, corresponding angles are equal, then their corresponding sides are in the same ratio and hence the two Triangles are-

• Always congruent

• Similar

• None of these

In the given figure ∆ACB~∆PQR, then find x.

• 13.5cm

• 15cm

• 21cm

• 5cm

If two angles of a triangle are respectively equal to two angles of another triangle, then by the angle sum property of a triangle their third angle will be-

• Unequal

• Equal

• Can't say

In the given figure, ∆QPR~∆YXZ, then find the angle Z.

• 60°

• 70°

• 50°
