Angles

What are angles?Or, when is an angle made?

What unit do we use when we measure angles?

Think of a circle e.g. the face of a clockHow many degrees are there in a full

turn?A half turn?A quarter turn?

What type of angle is this?

What shapes have right angles?

Types of Angles

Angles less than 90 are called acute angles.

Types of Angles

Angles greater than 90 but less than 180 are called obtuse angles.

Types of Angles

Angles greater than 180 are called reflex angles.

Activity on Moodle

For each example, correctly identify which type of angle it is.Find the task sheet on Moodle:Maths Entry Level > 2D Shapes and Angles >
