Understanding Angles
- Angles are everywhere. An angle is formed when two straight lines intersect.
- Look at the picture below. Two pairs of pencils create angles - can you identify which ones?
- If you answered the pair on the left and the pair on the right, you're correct! The middle pair doesn't form an angle because the lines don't meet.
- The picture below shows a right angle. This type of angle represents a quarter of a full turn.
- You can verify if an angle is a right angle by using a set square, as shown in the picture below.
- Therefore, three right angles make up three-quarters of a full turn...
- And four right angles complete a full circle.
Types of Angles
An angle represents a measure of rotation and is typically denoted in degrees (°). A full circle comprises 360°. A protractor is a tool used to determine the size of an angle.
Acute Angles
- Acute angles are those that measure less than 90°.
- Example: An angle of 30° is considered acute.
Obtuse Angles
- Obtuse angles fall between 90° and 180°.
- Example: An angle of 120° is an obtuse angle.
Reflex Angles
- Reflex angles span greater than 180° but less than 360°.
- Example: An angle of 270° is a reflex angle.
Right Angles
- A right angle precisely measures 90°.
- Example: A corner of a square forms a right angle, measuring 90°.
