Question

Types of angles and their defention​

Answer 1

Answer:

. Acute Angle:

An angle whose measure is less than 90° is called an acute angle.

. Right Angle:

An angle whose measure is 90° is called right angle.

In other words, an angle which measure exactly 90° is called a right angle.

Two lines that meet at a right angle are called perpendicular lines.

. Obtuse Angle:

An angle whose measure is greater than 90° but less than 180° is called an obtuse angle.

In other words, an angle measuring between 90° to 180° is called an obtuse angle.

Straight Angle:

An angle whose measure is 180° is called a straight angle.

In other words, an angle which measures exactly 180° is called a straight angle.

Reflex Angle:

An angle whose measure is more than 180° but less than 360° is called a reflex angle.

Zero Angle:

An angle measure 0° is called a zero angle.
