What are supplementary angles When the sum of two angles is 180°, then the angles are known as supplementary angles. The Lesson: In the triangle shown below, the angles A and B are complementary because they have a sum of 90º. We can think of these as opposite angles formed by an X. Vertical angles are two angles whose sides form two pairs of opposite rays. This concept is linked to the idea that on a circle the 90 degree complementary angle comes before the 180 degree supplementary angle. This is because we know that two angles on a straight line equal 180 degrees. So if you have a straight line with two angles on it, and you know the size of one of the angles, you can work out the size of the other by subtracting this from 180 degrees. One clue for remembering the difference between complementary and supplementary angles is to use the alphabet. Supplementary angles are two angles whose sum is 180 degrees (a straight angle). So if you have an angle that is 20 degrees, then the complement angle measures 70 degrees. The measure of the complement of any angle A is ninety degrees minus the measure of angle A. The measure of the complement is 12 more than twice the original angle. How do you find the measure of the complement of an angle?.The sum of all 3 interior angles of a triangle is equal to 180°.

Mark the degree of the angle made where two sides of the straight line intersect.Draw a straight line joining those two points, O and B.Now mark the point as B on the top circular part of a protractor, according to the preferred angle for example 40°.Now, place the protractor at that point, and its midpoint should touch the marked point O.How to Construct an Angle (using protractor) Wall clocks use the concept of angles to show time with hour and minute hands.Artists use their measurement knowledge to sketch or create art pieces.Carpenters use it to make equipment like doors, chairs, sofas, tables, etc.
