## What Are Mathematical Proofs?

Mathematical proofs are used to justify theorems. Arguments are set of statements that represent a proof. Symbols are used to represent mathematical arguments.

In the figure, a right-angled triangle PQR is shown. The three angles are related as,

∠PQR+ ∠QPR+ ∠PRQ =180˚

Angle Q is right-angled. Therefore,

∠QPR+ ∠PRQ = 90˚
