Worked Solution & Example Answer:Here is a rhombus - OCR - GCSE Maths - Question 3 - 2021 - Paper 1
Step 1
On the diagram, draw all of the lines of symmetry.
Answer
To draw the lines of symmetry of a rhombus, start by recalling that it has two diagonals that intersect at right angles. Therefore, the lines of symmetry will be:
- The first diagonal (from one vertex to the opposite vertex).
- The second diagonal (from the other pair of opposite vertices).
These lines divide the rhombus into mirror-image halves.
Step 2
Write down the order of rotation symmetry of the rhombus.
Answer
The order of rotation symmetry of a shape is defined as the number of times it can be rotated to look the same within a full 360-degree rotation. For a rhombus, the order of rotation symmetry is 2, meaning that you can rotate the rhombus by 180 degrees and it will look the same.
