Q3 of 70 Page 120

The correspondence ABC ↔ PQR between Δ ABC and Δ PQR is a similarity. AB : PQ = 4 : 5. If AC = 6, then find PR. If QR = 15, then find BC.

Given, ΔABC and ΔPQR

And AB : PQ = 4 : 5


AC = 6 and QR = 15


The correspondence ABC PQR between ABC and PQR is a similarity.


Hence,



PR =


PR = 7.5


And



BC =


PR = 12

According to the definition of similarity of triangles, which are the conditions for correspondence DEF ↔ ZXY between ΔDEF and ΔXYZ to be a similarity?

 2

For ΔPQR and ΔXYZ, the correspondence PQR ↔ YZX is a similarity. m∠P = 2m∠Q and m∠X = 120. Find m∠Y.

 4

Δ PQR ~ ΔDEF for the correspondence PQR ↔ EDF. If PQ + QR = 15, DE + DF = 10 and PR = 6, find EF.

 5

In ΔABC and ΔPQR, ABC ↔ QPR is a similarity. The perimeter of AABC is 15 and perimeter of ΔPQR is 27. If BC = 7 and QR = 9, find PR and AC.
