Q#1.

What is a Right, Acute, Obtuse, Straight, Reflex, Full, Complementary, Supplementary angles?

Dear Student

Acute-An acute angle lies between 0 degree and 90 degrees, or in other words; an acute angle is one that is less than 90 degrees.

Right-A right angle is always equal to 90 degrees. Any angle less than 90 degrees is an acute angle whereas any angle greater than 90 degrees is an obtuse angle.

Reflex-Any angle that has a measure which is greater than 180 degrees but less than 360 degrees (which coincides with 0 degrees) is a reflex angle.

Obtuse-The angle that measures greater than 90 degrees is obtuse. For example, 145° is an obtuse angle.

supplementary-If the sum of two angles is equal to 180°, then they are supplementary angles

complementary-If the sum of two anglesis equal to 90 they are called complementary angles.

Straight-A straight angle is 180 degrees when measured.
