Shapes And Patterns

In this article, we will learn mainly about Shapes and the learning objectives are:

  1. Identify shapes
  2. Identify 3D shapes
  3. Identify flat and curved surfaces

1. Identify Shapes

Recap: Can you identify the name of these 2D shapes?

Different shapes

Note:

A square has 4 equal sides of the same length. However, a rectangle has 2 long sides and 2 short sides.

Two half circles will make one circle. 

Four quarter circles will make one circle.

Answer:

(3) Half circle and triangle

 

Question 3:

How many quarter circles are there in the figure?

How many quarter circles are there in the figure

  1. 5
  2. 6
  3. 7
  4. 4

Answer:

(2) 6

 

2. Identify lines and curves

There are two types of lines - straight lines and curved lines.

  • A square has 4 straight lines and 0 curved lines.
  • A rectangle has 4 straight lines and 0 curved lines.
  • A triangle has 3 straight lines and 0 curved lines.

 

  • A circle has 1 curved line and no straight line.
  • A half circle has 1 straight line and 1 curved line.
  • A quarter circle has 2 straight lines and 1 curved line.

Question 1:

Which of the following shapes have the same number of straight lines?

Which of the following shapes have the same number of straight lines

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

Solution: 

The number of straight lines in A is 6, B is 8, C is 16 and D is 8. 

Answer:

(4) B and D

 

Question 2:

Which of the following shapes have the same number of curved lines?

Which of the following shapes have the same number of curved lines

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

Solution: 

The number of curved lines in A is 2, B is 0, C is 3 and D is 2. 

Answer:

(3) A and D.

 

Question 3:

How many curved lines are there in the figure below?

How many curved lines are there in the figure below

  1. 8
  2. 10
  3. 11
  4. 12

Answer:

(4) 12

 

 

Question 4:

How many more straight lines than curved lines are there in the figure below?

How many more straight lines than curved lines are there in the figure below

  1. 5
  2. 8
  3. 10
  4. 13

Solution: 

The number of straight lines \(= 13 \)

The number of curved lines \(= 5\)

Difference in number of straight lines and curved lines

\(= 13 - 5\)

\(= 8\)

Answer:

(2) 8

 

Question 5:

How many more straight lines than curved lines are there in the figure below?

How many more straight lines than curved lines are there in the figure

  1. 6
  2. 8
  3. 10
  4. 16

Solution:  

The number of straight lines \(= 16\)

The number of curved lines  \(= 6\)

Difference in the number of straight lines and curved lines

\(= 16 - 6\)

\(= 10\)

Answer:

(3) 10

 

3. Identify 3D Shapes

cute cube

A cube has six sides and each of them is a square.

Example: A Rubik’s cube, A dice etc.

 

Cute cuboid

Example: Baseball, A ping pong ball etc.

 

Cute cylinder

This is a cylinder and it has two circles on each side with a tube in between. 

Examples: A Coca-Cola can, A toilet paper roll, An unsharpened pencil etc.

 

Question 1:

Which two solid shapes are used to make the figure below?

Cone and cylinder

  1. Cone and cube
  2. Cone and cylinder
  3. Cube and cylinder
  4. Cube and cuboid

Answer:

(2) Cone and cylinder

 

Question 2:

Which three solids are used to make the figure?

Which three solids are used to make the figure

  1. Sphere, cone, cube
  2. Cone, cube, cylinder
  3. Sphere, cylinder, cuboid
  4. Cone, cylinder, cuboid

Answer:

(4) Cone, cylinder, cuboid

 

Question 3:

How many cubes more than spheres are there in the figure?

how many cubes more than spheres are there in the figure

 

  1. 1
  2. 6
  3. 3
  4. 9

Solution: 

The number of cubes \(= 6\)

The number of spheres \(= 3\)

Difference in number of cubes and spheres

\(= 6 - 3\)

\(= 3\)

Answer:

(3) 3
