Step 1: Use a protractor
A protractor is a tool used to measure angles. It has two scales, one on each ray of the angle, that meet at a point called the vertex. To determine if an angle is a right angle using a protractor, follow these steps:
Step 2
Place the center point (or vertex) of the protractor on the angle's vertex.
Final Answer
An angle is a right angle if it measures 90 degrees when measured with a protractor, if it is formed by two lines with negative reciprocal slopes, or if it is formed by two lines that create congruent (equal) angles with a transversal line.
