Geometry - Week 10: Lesson 2: Recognising Angles

In this lesson, we will discuss three main types of angles: acute, right, and obtuse angles. Angles are measured in degrees. There are 360 degrees in a full rotation of a circle. 

Here is a useful website that explains degrees

 

An Acute Angle (spetsig vinkel) is less than 90° 

A Right angle (rät vinkel) is exactly 90°

An Obtuse Angle (trubbig vinkel) is more than 90° but less than 180°
