Question

△DEF≅△PQR

What is the length of PQ?

(DF is 25cm and RQ is 24cm)

Answer 1

Since the triangles are similar, they have the same ratio to all corresponding sides. Let's find the ratio of ΔDEF to ΔPQR.

DF/RQ = 25/24

Similarly,

DE/PQ = 25/24

Thus, 

PQ = 24/25 DE
PQ = 0.96DE

This means that the length of PQ is 96% of the length of DE.
