Lesson details
Key learning points
- There are 90 degrees in a right angle
- Acute angles are between 0 and 90 degrees
- Obtuse angles are between 90 and 180 degrees
- Reflex angles are greater than 180 degrees
Keywords
Degrees - A degree is a unit of measure for angles.
Estimate - To estimate is to find a value that is close enough to the right answer, usually with some thought or calculation involved.
Common misconception
90 degrees is classified as an acute angle and 180 degrees is classified as an obtuse angle.
Provide opportunities for pupils to classify angle sizes and build towards understanding that acute angles are between 0-89 degrees and obtuse angles are between 91-179 degrees. Classifying multiples of right angles as a separate group may help.
