Question

 

In the given figure, the circle touches the sides of the quadrilateral PQRS. If PQ = a and RS = b, express (PS + QR) in terms of a and b?

• A. (a + b)/2
• B. 2 (a - b)
• C. a + b
• D. 2 (a + b)

Answer 1

Answer:

C. a + b

PZ = PW = p SZ = SY = q QW = QX = r RX = RY = s PQ + RS = p + r + s + q = a + b PS + QR = p + q + r + s = a + b
