Answer 2

The angle measuring $90^{o}$ is called a right angles triangle.

Explanation:  

• The angle measuring $90^{o}$ is called a right angles triangle.
• We can also represent it as $\frac{\pi }{2}$
• We can easily measure a right angle using a protector, try square, and set squares.
• Some examples of right-angle are when a clock strikes 9:30, notebook, edge of television, etc.
• We can identify a right angle by placing a protector on the edge of the product and seeing if the line strikes $90$ degrees.
• Therefore, $90$-degree angle is a right angle.
