Angles

The students in Year Five have been learning about the different types of angles.

Acute Angle: an angle that is less than 90°

Right Angle: an angle that is exactly 90°

Obtuse Angle: an angle that is greater than 90° but less than 180°

Straight Angle: an angle that is exactly 180°

Reflex Angle: an angle that is greater than 180° and less than 360°

Revolution: a 360° angle, a full rotation, a complete turn so it points back the same way

What have you learnt about angles?

What types of angles can you see in your house or apartment?

Miss Azzopardi can see a right angle in every corner of the room and in every corner of the door. She can also see a straight angle on each shelf of her bookshelf, the picture frame on her desk is leaning to create an acute angle and the door is open enough to create an obtuse angle.
