Worksheet Overview

QUESTION 1 of 10

A line of symmetry divides a shape into two matching parts, which will overlap each other exactly when folded along the line of symmetry.

When we complete shapes to make them symmetrical, we must reflect each corner in the line of symmetry.

In this worksheet, the lines of symmetry will be slanting.

Make sure that to reflect carefully. Each corner moves in a direction which is at right angles to the fold.

 

Look at this shape.

 

Mirror line

To complete the symmetry of the shape, we reflect each corner in the line m.

Notice that the blue lines are at right angles to the red line of symmetry m.

 

  Symmetrical shape

 

The next shape has been completed incorrectly.

Notice that the blue lines are NOT AT RIGHT ANGLES to the red line of symmetry m.

Incorrect symmetrical shape

 

 

This is how it should be completed.

Notice that the blue lines are at right angles to the red line of symmetry m.

 

 

Correct symmetrical shape

Look at this shape.
