An angle whose measure is between 0 and 90 degrees.

Adjacent angles
|
A pair of angles that share a vertex and a side. These angles are side by side.
|
You can remember this because the term adjacent means "side by side."
|
|
|
Complimentary angles
|
angles whose measures add up to 90 degrees.
You can remember these angles make a right angle because their shape is similar to the shape of a corner of a sheet of paper. |
Complementary starts with co- and so does corner.
|
|
|
Obtuse angle
|
An angle whose measure is between 90 and 180 degrees.
|
|
|
|
Right angle
|
An angle whose measure is exactly 90 degrees.
|
|
|
|
Straight Angle
|
An angle whose measure is exactly 180 degrees.
|
|
|
|
Supplementary angles
|
angles that add up to 180 degrees.
|
You can remember this because a 180 degree angle is a straight angle. Straight angle starts with s and so does supplementary.
|
|
|
