Ray: Has a endpoint and extends indefinitely in one direction
Intersection: Set of points that figures have in common
Vertex: The endpoint that 2 rays share
Sides: The rays that make up an angle
Acute: Angle which measure is greater than 0° and less than 90°
Obtuse: Angle which measure is greater than 90° and less than 180°
Right: Angle that is exactly 90°
Straight: Angle that is exactly 180°
Congruent Angles: Angles that have the same measure
Complementary Angles: Two angles whose sum is 90°
Supplementary Angles: Two angles whose sum is 180°
Adjacent Angles: Two angles that share a vertex
Linear pair: Two adjacent angles whose noncommon sides are opposite rays
Polygon: Closed plane figure with 3 or more line segments (sides)
Convect Polygon: No line that contains a side of the polygon contains a point in the interior of the polygon
Equilateral: All sides are congruent
Equalangular: All angles are congruent
Conjecture: Unproven statement based on an observation
Conditional Statement: A logical statement that has 2 parts, hypothesis and conclusion, and can be written in 'if-then' form
Negation: The opposite of the original statement
