Question

· PQR is an isosceles triangle inscribed in a circle.
Calculate the radius of the circle if PQ = PR =
50 cm and QR = 60 cm. please answer bata do ​

Answer 1

Answer:

Since, PQR is an isosceles triangle and PS ⊥ QR,

therefore it divides QR into two equal parts.

In ΔPSQ, ∠S = 90°

∴ PQ2 = PS2 + QS2 ....(By Pythagoras Theorem)

⇒ PS2 = PQ2 - QS2

= 102 - 62

= 100 - 36

= 64

⇒ PS = 8cm.
