Question

If PQR is an equilateral triangle and PX is perpendicular to QR, then PR^2 is equal to:
a) 3/2 RX^2
b) 2 RX^2
c) 3 RX^2
d) 4 RX^2

Answer 1

PQR is an equilateral triangle therefore perpendicular PX will bisect the side QR into two equal halves.
Let PQ=QR=PR=a
Then RX=a/2
PR^2=a^2
RX^2=a^2/4
So PR^2=4RX^2
