Question
In a triangle PQR, ST is drawn parallel to side QR. If
PS = 8 cm, QS = 5 cm and PT = 14 cm, then find PR.Solution
A line drawn parallel from two sides of a triangle to its third side divides the sides in same proportion.
So, (PS/QS) = (PT/RT)
Or, (8/5) = (14/RT)
Or, RT = 8.75 cm
So, PR = 14 + 8.75 = 22.75 cm
