Angles

TermDefinition
Ray A ray is a part of a line that begins at a particular point (called the endpoint) and extends endlessly in one direction.
Angle An Angle is the figure formed when two rays meet at a common endpoint.
Central Angle A Central Angle is an angle with its vertex at the center of a circle.
Right Angle A Right Angle is an angle that has a measure of 90 degrees.
Straight Angle A Straight Angle is an angle that has a measure of 180 degrees.
Acute Angle An Acute Angle is an angle that that has a measure of more than 0 degrees but less than 90 degrees.
Obtuse Angle An Obtuse Angle is an angle that that has a measure of more than 90 degrees but less than 180 degrees.
Complementary Angles Two Angles are Complementary if their measures add up to 90 degrees (a Right Angle).
Supplementary Angles Two Angles are Supplementary if their measures add up to 180 degrees (a Straight Angle).
Congruent Angles Two angles are Congruent if their measures are equal.
Vertical Angles Two angles are Vertical if they are formed by intersecting lines and are opposite each other.
Parallel Lines Parallel lines are two lines on a plane that never intersect and have the same slope.
Transversal A transversal is a line that crosses at least two other lines.
Corresponding Angles When two lines are intersected by a transversal, the angles that match from one group to the other are called corresponding angles.
Alternate Interior Angles When two lines are intersected by a transversal, the pairs of angles on opposite sides of the transversal but inside the two parallel lines are called Alternate Interior Angles.
Alternate Exterior Angles When two lines are intersected by a transversal, the pairs of angles on opposite sides of the transversal but outside the two parallel lines are called Alternate Interior Angles.
