Math lesson 7 shapes - square rectangle triangle

At school I love shapes because they had so much that you could learn and it was very interesting.

Shapes are lines in a certain order.

Shapes are useful to know so you can make things and place them together like a puzzle.

A square has 4 sides. The sides are exactly the same as each other. Each angle has to be a right angle.

A triangle has three sides. Its angles are acute and obtuse.

A rectangle  has four sides. Each angle has to be right angles. two sides are longer than the other two sides.
