Point - a specific location in space, Line - a set of points that form a straight path that goes in opposite directions without ending, Line segment - part of a line between two points on the line, called endpoints of the segment, Vertex - Point where two rays meet, Ray - part of a line that begins at one endpoint and continues without end in one direction, Angle - two rays with a common endpoint (the vertex), Parallel lines - lines that lie in the same plane, never intersect, and are always the same distance apart, Perpendicular lines - lines that intersect at right angles to each other to form square corners, Intersecting lines - lines that meet or cross at a point, acute angle - an angle measuring less than 90°, acute triangle - a triangle with three acute angles, compose - to form a larger angle by putting angles together, decompose - to cut an angle into smaller angles, degree - a unit used to measure the size of an angle, obtuse angle - an angle measuring more than 90° and less than 180°, obtuse triangle - a triangle that has one angle with a measure greater than 90°, protractor - a tool used to measure angles, right angle - an angle with a measure of 90°, right triangle - a triangle with one right angle, straight angle - an angle with a measure of 180°, side congruency marks - side marks showing the sides with the same measure, Polygon - a closed figure with at least 3 sides where all sides are straight (no curves), Regular figure - a polygon with all sides and angles congruent, Two-dimensional figure - a figure with two basic units of measure usually length and width, Classify - applying an attribute to categorize a figure in a sorted group, Congruent - of equal measure having exactly the same size and shape, Line of symmetry - line dividing an image into two congruent parts that are mirror images of each other,
