Test: Symmetry & Nets - 1 - Question 1

State the order of rotational symmetry

Detailed Solution for Test: Symmetry & Nets - 1 - Question 1

Each 90 degrees rotation of the given polygon returns to the original shape, so the polygon has an order of rotational symmetry of 4.

Test: Symmetry & Nets - 1 - Question 2

Which of the following shows reflection symmetry?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 2

Reflection symmetry is a type of symmetry where one-half of the object reflects the other half of the object. Option (a) fulfils this condition.

Test: Symmetry & Nets - 1 - Question 3

Which of the following is a line of symmetry of the figure?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 3

A line of symmetry is defined as the line which divides the figure into two equal mirror images
Hence from the above figure line L, line M, line N, line O are the lines of symmetry.

Test: Symmetry & Nets - 1 - Question 4

Choose the correct net for cone?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 4

The net of a cone consists of the following two parts:

  • a circle that gives the base; and
  • a sector that gives the curved surface.

Test: Symmetry & Nets - 1 - Question 5

Which of the following figure(s) does/do not have a line of symmetry?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 5

From the above figure we can say that figure P and Q do not have line of symmetry.

Test: Symmetry & Nets - 1 - Question 6

State the order of rotational symmetry

Detailed Solution for Test: Symmetry & Nets - 1 - Question 6

The shape will look like its original only once after you rotate the shape 360 degrees. Hence, it's rotational symmetry is 1.

Test: Symmetry & Nets - 1 - Question 7

What is the least number of squares that must be added, so that the line AB becomes a line of symmetry?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 7

From the above figure minimum 2 squares should be added so that line AB becomes a line of symmetry.

Test: Symmetry & Nets - 1 - Question 8

Which square must be shaded so that the figure has a line of symmetry?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 8

From the above figure, it can be shown that the square P should be shaded so that the above figure has a line of symmetry.

Test: Symmetry & Nets - 1 - Question 9

State the order of rotational symmetry

Detailed Solution for Test: Symmetry & Nets - 1 - Question 9

The shape will look like its original only once after you rotate the shape 360 degrees. Hence, it's rotational symmetry is 1.

Test: Symmetry & Nets - 1 - Question 10

Which of th following does not have an order 4 of rotational symmetry?

Detailed Solution for Test: Symmetry & Nets - 1 - Question 10

Rotational symmetry of order 4 is in (b) and (c) because in these figures, in a complete turn of 4 number of times, the object would be looking exactly the same. However, (a) only has a rotational symmetry of 1.
