Test: Geometry- 2 - Class 4 MCQ

Angles between 0 and 90 degrees (0°< θ <90°) are called acute angles. Angles between 90 and 180 degrees (90°< θ <180°) are known as obtuse angles.

The angle of a straight angle is usually 180°. Whenever two rays join together they form an angle.

Clock shape is a complete angle.

90 degrees constitute a right angle. 

A point is an exact location in space. A point is denoted by a dot. A point has no size.

The inside of an angle is called interior angle. 

The outside of an angle is called exterior angle. 

The rays start from the sun and go in all directions without ending in one point. Thus, a ray has one endpoint.

An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc.

The flag post is always perpendicular to the ground.
