Question

In triangle PQR, PM is perpendicular to RQ and N is a point on PM. Which of the following relations holds good?

• A. $R{N}^2+Q{N}^2=P{R}^2+P{Q}^2$
• B. $R{N}^2+P{R}^2=Q{N}^2+P{Q}^2$
• C. $R{N}^2+P{Q}^2=P{R}^2+Q{N}^2$
• D. $R{N}^2-P{Q}^2=P{R}^2-Q{N}^2$

Answer 1

The correct option is C $R{N}^2+P{Q}^2=P{R}^2+Q{N}^2$
