Question

define acute angle, obtuse angle, right angle, straight angle, reflex angle with example​

Answer 1

Acute Angle - An angle less than 90 degrees.Ex 85°

Right Angle - An angle that is exactly 90 degrees. Ex 90°

Obtuse Angle - An angle more than 90 degrees and less than 180 degrees. Ex 100°

Straight Angle - An angle that is exactly 180 degrees. Ex 180°

Reflex Angle - An angle greater than 180 degrees and less than 360 degrees. Ex 300°

Answer 2

Answer:

Acute angle : When the measure of an angle is more than 0 degree and less than 90 degree then it is known as acute angle.

Right angle : When the measure of an angle is equal to 90 degree is called right angle.

Straight angle : When the measure of an angle is equal to 180 degree it us known as straight angle.

Reflex angle : When the measure of an angle is more than 180 degree but less than 360 degree it is known as reflex angle.
