In Euclidean geometry a right angle is an angle that the angle made between the arms of the angle is equal to the angle adjacent to it. This angle is ninety degrees.
The right angle bisects the angle of the line into two equal parts.
The right angle is demonstrated:
Given a line DC with point B lying on it Take B as the vertex of angle ABC If the angle ABC equals the angle ABD then angle ABC is a right angle, and so is angle ABD
