If ∆ABC ~ ∆RPQ, AB = 3 cm, BC = 5 cm, AC = 7 cm, RP = 9 cm and PQ = 15 cm, then find

QR

In ∆DEW, AB || EW. If AD = 4 cm, DE = 16 cm and DW = 24 cm, then find the value of DB.

In an equilateral triangle of side 3√3 cm, find the length of the altitude.

Which of the following statement is false?

A ladder 25 m long just reaches the top of a building

24 m high from the ground. What is the distance of

the foot of ladder from the base of the building?

In the ∆ABC , AB = 24 cm, BC = 10 cm

and AC = 26 cm, then ∆ABC is a right angle triangle.

If ∆ABC~∆DEF and their areas be 121 cm² and 64 cm² respectively, then find BC If EF = 16 cm.

∆ ABC is similar to

Sides of two similar triangles are in the ratio 2:8. Areas of these triangles are in the ratio
