two of the angles are equal as

shown in the diagram on the left.

Tangents are external lines which

touch the circumference of a circle
at one place. Very often you will see

converging tangents

(intersecting to a point)
as shown in the

diagram on the left. You

are now going to create
a circle with two

tangents and measure the angles between them.

Exercise 5.2

1. Draw a circle of radius 5 cm to the left an A4

page.
2. Use a set square to draw a radius from the

centre to the south point.

3. Draw a horizontal tangent line of length 14 cm
which passes through the south point. There

should be a right-angle between this line and the
