The question, in short

Circle geometry: name line AB using the word box, draw a radius on a circle, and find angle x from a diagram showing 130° at a point.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

Choose the correct term from the box that describes the straight line AB in the circle diagram.

  1. 1The line AB touches the circle at one point and is perpendicular to the radius at that point.
  2. 2Therefore, AB is a tangent.

Answertangent

Part (b) · 1 mark

On the given circle with centre O, draw a radius.

  1. 1Draw a straight line from the centre O to any point on the circumference of the circle.
  2. 2Ensure the line is clearly not a diameter.

AnswerRadius drawn

Part (c) · 1 mark

Using the diagram with one angle of 130°, calculate the size of the angle marked x.

  1. 1The angle around a point is 360°.
  2. 2Subtract the given angle 130° from 360°.
  3. 3360 − 130 = 230
  4. 4x = 230
