Answer: PN = 20 in.
Step-by-step explanation:
In the diagram two congruent triangles are given ΔPMN ≅ ΔQSR.
So by CPCTC (corresponding parts of congruent triangles are congruent)
In ΔPMN and ΔQSR
PN=QR=20 in.
PM=SQ=24 in.
MN=RS= 7 in.
Congruent triangles are the triangles of which all the sides and all the angles are congruent.
- If two triangles are said to be congruent then its all corresponding parts must be equal.
