Unit 8 Flashcards
Two angles sharing a common vertex and whose sides form pairs of opposite rays
Vertical angles
Two angles whose sum is 90°
Complementary angles
Two angles whose sum is 180°
Supplementary angles
A line intersecting two or more other lines
Transversal
Angles in the same relative position to one another (F)
Corresponding angles
Angles that are formed by a transversal and that are located between two intersected lines
Interior angles
Transversal (U)
Same side interior
Transversal (Z)
Alternate interior angles
Angles that are formed by a transversal and that are located outside the two intersected lines
Exterior angles
Formed by a pair of parallel lines and transversal; they are congruent
Alternate exterior angles
A corner if a polygon
Vertex
A polygon where any line segment connecting any two vertices must pass through the interior of the shape.
Convex polygon
A polygon where all at least one line segment connecting any two vertices passes through the outside of the shape
Concave polygon
A polygon where all sides are equal in length and all angles are equal in measure
Regular polygon
Calculating lengths using ratios of corresponding sides of similar polygons
Indirect measurement
