GEOM-041 Mod 6 Vocab Practice Exam Questions With 100% Correct Answers. Mathematical Proof A logical argument that uses previously proven statements to demonstrate that a new statement is true. Linear Pair Pair of angles that share a common side and add up to 180 degrees. When a straight line intersects with another straight line, any two adjacent angles in the intersection are linear pairs. Supplementary Angles Two angles whose sum is 180 degrees. Complementary Angles Two angl...

angle addition postulate If C is in <DBA, then <DBA = PDBC = <CBA definition of linear pair if two angles form a linear pair, then their noncommon sides are opposite rays definition of straight angle if two sided of an angle are opposite rays, then the measure of the angle is 180* definition of complementary angles If <b and <c are complementary, than <b+<a=90*, then <b and <a are complementary. defenition of right angle If two sides of...

Mathematics for Elementary Educators III - D127 Images included vertical line A line that runs up and down on the coordinate plane, parallel to the yaxis. It has no run, or change in x-value. complementary angles Two angles whose sum is equal to 90°. line A straight one-dimensional figure that extends infinitely in both directions. origin The point on a coordinate plane where the x-axis and y-axis intersect. Typically, the point represents 0 on both axes. tangent A straight...
