Question

What is the measure of the angles formed by two perpendicularly intersecting lines?

• A. All angles measure ${90}^o$
• B. All angles measure ${45}^o$
• C. Two angles measure ${90}^o$ and two measure ${45}^o$.
• D. None of these

Answer 1

The correct option is A All angles measure ${90}^o$

Measure of angles formed by two intersecting lines is ${90}^{\circ }$.

So option $A$ is correct.
