Compare sides and vertices in shape properties: Example question
31 October 2026
When learning about shapes, children often need to compare how many sides and corners (vertices) different shapes have. This helps them spot patterns and understand the properties of each shape clearly.
Example question
Shape A is a triangle. Shape B is a rectangle.
How many sides does each shape have?
A triangle has 3 sides.
A rectangle has 4 sides.
How many vertices does each shape have?
A triangle has 3 vertices.
A rectangle has 4 vertices.
Which shape has more sides and more vertices?
The rectangle has more sides and more vertices than the triangle.
Key insight: To compare shapes, count the sides and vertices of each shape, then see which number is bigger.
After working through this example, your child will be able to count sides and vertices in common shapes and compare them with confidence. They can now try similar questions to build their skills for 11+ shape properties practice. For more support, you can find resources by searching for maths.com uk.
