Free Introduction to Geometry 01 Practice Test - 4th Grade 

Question 1

We can say that the study of geometry starts with a ____.

A. line
B. point
C. angle
D. ray

SOLUTION

Solution : B

We can say that the study of geometry starts with a point. A point is an exact position in space. It is the basic unit of geometry. Any geometrical figure is a collection of infinite number of points.

Question 2

In geometry we study about

A. shapes
B. songs
C. angles
D. lines

SOLUTION

Solution : A, C, and D

We study about points, lines, angles, shapes in geometry.
Songs are not taught in geometry.

Question 3

When two lines cross each other at a point we call them ___ lines.

SOLUTION

Solution :

When two lines cross each other at a point we call them intersecting lines and the point where they meet is called the point of intersection.

Parallel lines never intersect each other. 

Question 4

We can find our way through a new city without knowing the directions. 

A. False
B. True

SOLUTION

Solution : A

When visiting a new city or place, it would help to know the directions to guide us around. A map can be very useful. It lets us know where we are and can also help us identify directions that will help in navigating through a city. 

Question 5

The opposite edges of a desktop screen are  ___.

A. parallel lines
B. zigzag lines
C. vertical lines
D. diagonal lines

SOLUTION

Solution : A


The opposite edges of a desktop screen are always equally spaced and do not meet.

They are thus, examples of parallel lines.

Question 6

A 90-degree angle is also called a ___ angle.

SOLUTION

Solution :

A 90-degree angle is also called a right angle.

Question 7

A straight angle is ___ a reflex angle.

A. greater than
B. less than
C. equal to
D. bigger than

SOLUTION

Solution : B

A straight angle measures 180°.

A reflex angle measures more than a straight angle of 180°, but less than a full circle of 360°.

Hence, a straight angle is less than a reflex angle.

Question 8

What is an angle that measures 360∘ called?

A. Whole angle
B. Obtuse angle
C. Straight angle
D. Right angle

SOLUTION

Solution : A

  • An angle which measures 360∘ is  called a whole angle.Understanding Angles and its Types – MathsTips.com
  • An angle which meaures greater than 180∘ and less than 270∘ is called an obtuse angle.Measuring angles with a protractor - lesson & video
  • An angle which measures 180∘ is called a straight angle. Straight Angle Definition, Properties, Construction, and Examples
  • An angle which measures 90∘ is called a right angle. Shapes with Right Angles - Video & Lesson Transcript | Study.com

Question 9

What are lines that are always at the same distance from each other and never intersect called?

A. Horizontal lines
B. Parallel lines
C. Intersecting lines
D. Vertical lines

SOLUTION

Solution : B

Image result for parallel lines

When two (or more) lines are always at the same distance from each other and never intersect each other, they are called parallel lines.

The railway lines are examples of parallel lines.

Question 10

How many right angles make a straight angle?

A. 1
B. 2
C. 3
D. 4

SOLUTION

Solution : B

A right angle is equal to 90 degrees. 

A straight angle is equal to 180 degrees.

90×2=180

Hence, two right angles make a straight angle.
