Statement whose truth is accepted without proof is called. The transitive property states that every quantity is equal to itself: True or False? A polygon is a closed figure made of a number of. When the sides and interior angles of a polygon are equal, the polygon is called. Every triangle consists of three non-collinear points called and three line segments called. If two lines intersect each other, then the vertically opposite angles are equal: True or False? If a transversal intersects two lines, then each pair of corresponding angles are equal. The measures of two complementary angles have a ratio of 1:2. What is the measure of each angle? If angle Z1 is complementary to angle Z3, then both Z1 and Z3 are angles. If two angles have the same measure, then they are.
