Angle names
Students identify acute, right, obtuse, straight, reflex and complete-turn angles.

Angles practice app
A quick classroom-ready app for naming angles, recognising right angles, comparing angle sizes and deciding whether an angle is greater than or less than a right angle.
Right angles
Students decide whether a shown angle is exactly a right angle.
Greater or less
Students compare an angle with a right angle using less than, equal to or greater than language.
Compare angles
Students look at two angles and choose the angle with the greater amount of turn.
What students practise
The app gives short visual angle questions so students connect angle language with the amount of turn they can see.
- naming acute, right, obtuse, straight, reflex and complete-turn angles
- recognising whether an angle is a right angle
- deciding whether an angle is less than, equal to or greater than a right angle
- comparing two angles and choosing the larger angle
- using mixed practice when students are ready to choose the strategy
How it fits a lesson
Use it after modelling angle turns, during rotations, as a warm-up, or as a quick check before students measure or construct angles.
- start with right-angle questions when students are building the benchmark
- use greater or less questions to connect size with the right-angle reference
- move to angle names once acute, obtuse, straight, reflex and complete turn are being introduced
- use compare angles when students need to focus on amount of turn, not arm length
Why it helps
Angle work becomes stronger when students use a benchmark and talk about the amount of turn rather than guessing from the picture.
- builds right-angle benchmark language
- connects angle names to visual examples
- helps students compare angle size carefully
Frequently Asked Questions
Is the angles practice app free?
Yes. Students, teachers and families can open the angles practice app in a browser for free.
Which angle names are included?
The app includes acute, right, obtuse, straight, reflex and complete-turn angles.
What question types are included?
Students can practise angle names, right-angle recognition, greater than or less than a right angle, comparing two angles, or mixed practice.
Does the app measure angles with a protractor?
No. This app focuses on angle language and visual comparison. Use it before moving into protractor measurement or construction tasks.
