Question

Prove that if two angles are both right angles, then the angles must be congruent. ( Use a two-column proof ) Given: ∠S and ∠T are each right angles Prove: ∠S ≅ ∠T

Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
