what are the measures of angle a and angle b if angle a and angle b are supplementary angles and angle a congruent angle b?

Reflex Angle : An angle whose measure is more than 180 o and less than 360 o is called a reflex angle..

An angle is an amount of rotation of a half-line (or ray) in a plane about its end point from an initial position to a terminal position. The important terms are: Measurement of angle, Positive and Negative angles, Lines at right angles, Quadr..

In a given plane two lines intersect at only one point. The angles are measured with the help of a protractor. The measure of an angle is called its magnitud..
