Step 1
Triangle ABC is an isosceles triangle
an isosceles triangle is a triangle that has two sides of equal length.
Step 2:
Step 3:
Since PQ//AC and RQ//AB hence, angle PBQ and RCQ are isosceles triangle with sides 10, 10, 6,
Perimeter of APQR is the sum of the length of the outer length of APQR.
Perimeter of APQR = AP + AR + QP + QR
=10 + 10 + 10 + 10 = 40
Final answer
Perimeter of APQR = 40
