Part - Smaller piece of a whole image, Whole - Image made up of smaller pieces, Length - A measurement of linear distance or extent, Between - A span not including endpoints, Bisect - To divide into two equal parts or halves, Reflexive - A relation where every element of a set is related to itself, Transitive - A relationship between three elements (a, b, and c) where if a is related to b, and b is related to c, then a must also be related to c, Symmetric - For a geometric shape, this means it can be divided into identical parts that are mirror images of each other or match perfectly after a rotation or slide. In set theory or algebra, a relation is symmetric if, for any elements A and B, A being related to B implies that B is related to A., Given - Conditions or facts assumed to be true at the start of a problem or proof, serving as the established basis for further reasoning or calculations, Reason - The process of logical deduction to derive a conclusion from premises, Statement - A declarative sentence that is either true or false, but not both, Prove - To demonstrate its truth by constructing a formal argument that uses previously proven statements, following strict rules of logical deduction, to logically guarantee a specific conclusion, Obtuse - An angle greater than 90 degrees but less than 180 degrees, Complementary - Two or more angles that add to 90 degrees, Supplementary - Two or more angles that add up to 180 degrees, Line (Straight Angle) - An angle measuring exactly 180 degrees, Across - Opposite from, Vertical Angles - Pairs of opposite angles made by intersecting lines; vertical angles are congruent, Linear Pair - A set of adjacent angles whose non-common ray form a straight angle, Angle Addition Postulate - The sum of the measures of two adjacent angles equals the measure of the larger angle formed by their combination, Segment Addition Postulate - If a point B lies on a line segment AC, then the sum of the lengths of the two smaller segments (AB and BC) equals the length of the entire segment (AC), Supplement Postulate - If two angles form a linear pair, then they are supplementary,
