GCSE Maths Practice: circle-properties

Question 9 of 10

This question teaches students to identify the main parts of a circle.

‹ ›

\( \begin{array}{l}\text{Which of the following are parts of a circle?}\end{array} \)

Select all correct options:

Remember: radius, diameter, circumference are circle-specific; diagonal is not.

The main parts of a circle include the radius (distance from center to any point on the circle), the diameter (twice the radius), and the circumference (distance around the circle). Understanding these parts is essential for calculating areas, circumferences, and for solving geometric problems. Diagonal is not part of a circle; it is a term used for polygons. Students should practise labelling diagrams with radius, diameter, and circumference to reinforce learning. Mastery of circle terminology ensures correct application in formulae and geometric constructions, improving both conceptual understanding and exam performance.
