KS2 Primary Maths Age 9-13 - Angles: - Explained

The video tutorial explains how to find the largest angle in a diagram with angles around a point. The problem involves angles labeled as 5X, X, X, and 2X, which sum to 360 degrees. The instructor sets up an equation, solves for X, and calculates the largest angle as 200 degrees. Key points include setting up the equation and understanding that angles around a point sum to 360 degrees.

What is the total sum of angles around a point?

• 360 degrees

• 270 degrees

• 450 degrees

• 180 degrees

If the angles around a point are represented as 5X, X, X, and 2X, what equation can be formed?

• 5X + X + X + 2X = 360

• 5X + X + X + 2X = 270

• 5X + X + X + 2X = 180

• 5X + X + X + 2X = 450

What is the value of X if 9X equals 360?

• 60

• 40

• 30

• 50

How do you calculate the largest angle if X is 40?

• Multiply 5 by 30

• Multiply 5 by 40

• Multiply 5 by 60

• Multiply 5 by 50

What is the size of the largest angle in the problem?

• 150 degrees

• 180 degrees

• 200 degrees

• 250 degrees
