Missing Angles round a point

Understanding the concept of missing angles around a point is a fundamental aspect of geometry that is often introduced at the KS2 level. This topic involves recognising that the sum of angles around a single point, or at a full turn, always adds up to 360 degrees. Students are typically presented with a series of angles around a point, some of which are known and marked in degrees, while others are missing. The aim is to calculate the missing angles by considering the sum of the given angles and subtracting this from 360 degrees.

For example, if students are given angles of 45°, 35°, 87°, and 167° around a point, they would first add these angles together to find the total of the known angles. After calculating this sum, they would then subtract it from the total 360 degrees that represent a full circle around the point. The result would be the value of the missing angle. This exercise not only helps in reinforcing the properties of angles around a point but also provides practice in basic arithmetic operations such as addition and subtraction. It's an engaging way for students to apply their mathematical knowledge to solve problems and enhance their understanding of geometric principles.
