Question

In triangle ABC, P is the midpoint of AB, segment PR is parallel to segment BC, segment PQ is parallel to segment AC and AB=18 cm then find QR?
​

Answer 1

Answer:

in triangle abc ,

• ap=pb
• ap=pb=9cm(since p ic mid point)
• and point q is mid point of ac(by mid point thoeram)
• so ar=ac=9cm
• qr=1/2ab =1/2×18=9cm(by mid point thoeram)
