Circle Identification

A line intersecting a circle in two distinct points is called

• Tangent

• Secant

• Centre

• Radius

If two tangents are drawn from an external point then they subtend equal angles at the centre

• TRUE

• FALSE

The length of tangent from a point A at a distance of 5 cm from the centre of the circle is 4 cm. What is the radius of the circle?

• 2 cm

• 3 cm

• 4 cm

• 5 cm

The perpendicular at the point of contact of the tangent to a circle passes through the centre
