study
Less than 90 degrees
Acute Angle
90 degrees
Right Angle
Between 90 and 180 degrees
Obtuse Angle
180 degrees
Straight Angle
Between 180 and 360 degrees
Reflex Angle

Revolution
They share a common ray and vertex and are next to each other.
Adjacent Angles
Angles that add up to 90 degrees
Complementary
Angles that add up to 180 degrees
Supplementary
Angles that are opposite to each other, which makes them equal.
Vertically Opposite Angles
Lines that travel in the same direction and will never touch.
Parallel Lines
A line that crosses parallel lines
Transversal
An angle that makes an ‘F’ shape and the lines of the ‘F’, the angles are on the top part or bottom.
Corresponding Angles
An angle that makes a ‘Z’ shape and the angles are on the corners of the ‘Z’.
Alternate Angles
An angle that makes a boxy C and the angles are on the same line which would make them Supplementary (adds up to 180).
Co-interior Angles
