D and E are points on sides AB and AC of triangle ABC such that DE || BC and AD = 8 cm, AB = 12 cm and AE = 12 cm. Then the measure of CE will be:

If in ΔABC and ΔDEF ∠A = 50°, ∠B = 70°, ∠C = 60°, ∠D = 60°, ∠E = 70° and ∠F = 50° then the correct of the following is:

If ΔABC ~ ΔDEF and AB = 10 cm, DE = 8 cm then the ratio of area of ΔABC and area of ΔDEF will be:

The shadow of 12 cm long vertical rod on the ground is 8 cm long. If at the same time the length of the shadow of a tower is 40 m, then the height of the tower will be:

In ΔABC, D is a point on BC such that and ∠B = 70°, ∠C = 50° then find ∠BAD.
