ByComplementary angles. When two angles add up to 90° they are called complementary angles . a. b. a + b = 90°. Angle a and angle b are complementary angles . Supplementary angles. When two angles add up to 180° they are called supplementary angles . b. a. a + b = 180°.

ByAlgebra A. Lines and Angles. Lines. In Mathematics, a straight line is defined as having infinite length and no width. Is this possible in real life?. Labelling line segments. A. B. When a line has end points we say that it has finite length. It is called a line segment.

ByAngles. KHM. Polygons. Definition:. A closed figure formed by a finite number of coplanar segments so that each segment intersects exactly two others, but only at their endpoints. These figures are not polygons. These figures are polygons. Interior Angle of a Polygon.
