In the diagram, . Triangles P M N and Q S R are shown. The lengths of sides P N and R Q are congruent, the lengths of sides Q S and P M are congruent, and the lengths of sides M N and R S are congruent.

If QR = 20 in., RS = 7 in., and SQ = 24 in., what is PN?

3 in.
7 in.
20 in.
24 in.

PN= 20 in.

Step-by-step explanation:

Given: In triangles PMN and QSR :

Length of P N ≅ Length of RQ  (1)    [ '≅' → Sign of congruence]

Length of QS ≅ Length of PM

Length of MN ≅ Length of RS

By SSS congruence rule

ΔPMN ≅ ΔQSR

Since Length of QR =20 in. [Given]

From (1)

Length of PN= 20 in.  [Congruent means exactly equal]

the answer is 8

step-by-step explanation:

3.14 x 8x8

good luck!
