THE CURIOSI · EXPLORE & TRY

Explore the model, then test your understanding. Select each numbered stop to discover its role.

Learning diagram: use the labelled values. Screen size changes, so these pictures are not calibrated measuring tools.

1Quadrilateral

A quadrilateral is a polygon with four sides.

2Rectangle

A rectangle has four right angles.

3Rhombus

A rhombus has four equal sides.

4Square

A square has four right angles and four equal sides, so it is both a rectangle and a rhombus.

Use matching units and the stated properties. Explain whether your answer measures length, area or volume.

Choose one answer for each question, then check. Practice results stay on this page and do not change course completion.

1. Is a square also a rectangle in this property-based classification? Yes No Only if it is drawn upright

2. Is every rhombus a square? Yes, always Only if it is large No; right angles are also needed

3. Which is a polygon? An open curved line A closed triangle with straight sides A circle
