Angles on a straight line add that up to 180 degrees are called supplementary angles
straight angle.
Obtuse angle
An acute angle
Let's denote the measure of the angle as x degrees. The complementary angle would then be 90 - x degrees. According to the given information, we have the equation x = 14(90 - x). Solving this equation, we find x = 70 degrees and the complementary angle is 20 degrees.
revolution angle
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
An angle that is exactly 180 degrees is called a straight angle.

An obtuse angle measure in degrees is more than 90.
Acute angle is less than 90 degrees. Right angle is exactly 90 degrees. Obtuse angle is greater than 90 degrees, but less than 180 degrees. A straight angle is 180 degrees. We often call an angle that is greater than 180 degrees a reflex angle.

A bigger than 180 degrees angle
A 90-degree angle is commonly called a right angle.
