Complementary Angles
The sum of the measure of two angles is 90 degrees.
Supplementary Angles
The sum of the measure of two angles is 180 degrees.
Adjacent Angles
Angles that are next to each other. They share a vertex and a common side.
Vertical Angles
Angles opposite one another when two lines intersect.
transversal
A line that intersects two or more lines.
Parrallel Lines
Lines in the same plane that never intersect, equal distance apart
corresponding angles
Angles that have the same relative positions in geometric figures.
Exterior Angles
outside angles adjacent to the interior angles when the sides of a triangle are extended
interior angles
inside angles when sides of triangle are extended
alternate exterior angles
lines on different sides of the transversal, but on the outside of the lines cut by the transversal
alternate interior angles
Angles that lie within a pair of parallel lines and on opposite sides of a transversal; congruent
consecutive interior angles
..., If two parallel lines are cut by a transversal, then each pair of consecutive interior angles is supplementary
right angle
An angle that is 90 degrees (It makes a square in the corner).
Acute Angle
An angle that measures LESS than 90 degrees.
Obtuse Angle
An angle that measures MORE than 90 degrees
