Answer guide · AC9M1SP01
- A triangle.
- A circle has a curved boundary and no corners. A triangle has three straight sides and three corners.
- Accept two closed shapes, each with three straight sides; they may differ in size or side lengths.
- For example, a book cover; four straight sides, with opposite sides equal and four square corners.
If help is needed: A shape's name does not change just because it is turned or coloured differently. Use its sides and corners as evidence.
