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.

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

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:
