Measuring and drawing angles for 11+
Understanding how to measure and draw angles is an essential skill for the 11+ Maths exam. Children need to be confident with a protractor and able to work accurately.
How to measure an angle
Place the centre of the protractor exactly on the vertex of the angle.
Make sure one side of the angle lines up with the zero line on the protractor.
Read the number on the scale where the other side of the angle crosses the protractor. This is the size of the angle in degrees.
How to draw an angle of 65°
Draw a straight base line with a ruler.
Place the centre of the protractor on one end of the line, lining up the zero line with your base.
Find 65° on the protractor scale and make a small mark at this point.
Remove the protractor and use a ruler to join the end of the base line to the mark. This creates a 65° angle.
Worked example
Measuring a 50° angle: Place the protractor's centre on the angle's vertex. Line up one side with zero. The other side crosses at 50°.
Drawing a 50° angle: Draw a straight line. Place the protractor's centre at one end and mark 50°. Join the end of the line to the 50° mark with a ruler.
The correct answer is a clearly marked 50° angle.
Practising at home
Encourage your child to measure and draw a range of angles using a protractor and ruler. This builds confidence and accuracy for the 11+ exam.
Key insight: Practising measuring and drawing angles helps children become familiar with the protractor and the precision needed for 11+ success.
