Question

If PQR is an equilateral triangle and PX is perpendicular to QR, then PX^2 = ?

Answer 1

Answer:

Step-by-step explanation:

Given: Δ PQR is a Equilateral triangle.

          PX is perpendicular to QR.

To find: PX²

Figure is attached.

Δ PQR is Equilateral triangle

⇒ PQ = QR = PR

Also, In Equilateral triangle Perpendicular on a  side is median of that side.i.e., PX is also median.

⇒ QX = XR =

In Δ PXR

By Pythagoras Theorem,

 ( ∵ PR = QR )
