Question

Define zero angle.

Answer 1

Hint: The above questions asks us to define zero angle. A zero angle is a type of angle that has some specific property which makes it different from the other types of angle. In order to understand what a zero angle is, we will, at first learn about angles and its types.

Complete step-by-step answer:
Let us first learn what an angle is,
In geometry, the angle can be described as a figure made of two rays meetings at the common initial point.
There are seven types of angles based on their degree measurement. They include:

I.Angle Acute: An acute angle is an angle greater than 0° but less than 90°. Common examples of acute angles are: 15°, 20°, 55°, 80°, etc.

II.Angle of 90 degrees/Right angle: The 90-degree angle, also known as the right angle, is an angle strictly measuring 90°, called the right angle. Right angles are represented by drawing a small square box between the angled arms.

III.Obtuse angle: An obtuse angle is an angle measuring more than 90 degrees but less than 180 degrees. Examples of obtuse angles are: 95°, 110°, 130°, etc.

IV.Reflex angles: Reflex angles are angles measuring more than 180 degrees but less than 360 degrees.

V.Complete angle: complete angle is an angle strictly measuring 360 degrees.

VI.Angle Zero: The zero angle (0°) is the angle formed when the two arms of the angle are in the same position.

Note: An angle whose degree of measurement is greater than the degree of measurement of another angle is a greater angle. So we can say that: Zero angle is less than Acute Angle is less than Right Angle and likewise.
