Triangles Mock Tests

A triangle has sides 13 cm, 14 cm, and 15 cm. Find the altitude corresponding to the side of 14 cm.

In triangle PQR, if PQ = PR and angle P = 50°, then angle Q equals:

The area of a triangle with base 12 cm and height 5 cm is:

In △ABC, if ∠A = 90° and AB = AC, then ∠B is:

In triangle ABC, if AB = AC = 10 cm and BC = 12 cm, then the area of triangle ABC is:

In the figure, △ABC ∽ △PQR. If AB = 4 cm, PQ = 6 cm and Area(△ABC) = 36 cm², then Area(△PQR) is:

In the figure, triangle ABC is similar to triangle DEF. If AB = 4 cm, BC = 6 cm, AC = 5 cm, and EF = 9 cm, find the perimeter of triangle DEF.

If ∆ABC ~ ∆PQR and AB/PQ = 3, then ar(∆ABC)/ar(∆PQR) is:
