Test: Geometry- 1 - Class 4 MCQ

A flag is always perpendicular to the ground, not parallel. 

Hence, False. 

An acute angle is an angle that measures less than 90°. It can be measured using a protractor. For example, 35°, 60°, 72°, and so on are all acute angles.

Stumps of a wicket is an example of perpendicular. (with reference to ground)

- A part of a line is called a line segment.
- A line extends infinitely in both directions, but a line segment has two definite endpoints.
- Unlike a ray, which starts from a point and goes infinitely in one direction, a line segment is finite and measurable.

A reflex angle is any angle that is more than 180 degrees (half circle) and less than 360 degrees (full circle). A reflex angle will always have either an obtuse or an acute angle on the other side of it.

Ruler is an example of straight  angle.

In Maths, a straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line.

180 is a straight angle. 

A full angle, also called a complete angle, and 360 is a complete angle. 

Corner of room is right angle

All perpendicular lines are intersecting lines
