Angles: explained simply
An angle describes the opening between two rays with the same starting point. Identify its type, measure it or draw it.
How to work it out
- Acute: below 90°. Right: exactly 90°. Obtuse: above 90° and below 180°. Straight: exactly 180°. Reflex: above 180° and below 360°.
- To measure, place the protractor's centre on the vertex and its baseline along one arm. Read the scale that starts at 0 on that arm.
An example, step by step
An angle measures 120°. What type is it?
- Compare it with a right angle: 120° is greater than 90°.
- Compare it with a straight angle: 120° is less than 180°.
- It is an obtuse angle.
Understand other variations
Draw an angle
Draw the first ray. Place the protractor at its starting point, mark the required angle, such as 60°, and draw the second ray through the mark.
Angles above 180°
Check which opening the arc marks. A full turn is 360°. If the smaller opening is 90°, the larger one is 360° − 90° = 270°.
Your turn
What type of angle is 45°?
Show the answer and method
An acute angle, because 45° is below 90°.
