Question

Which theorem is used while constructing a tangent to the circle by using center of a circle?

Options

• Tangent – radius theorem.

• Converse of tangent – radius theorem.

• Pythagoras theorem.

• Converse of Pythagoras theorem.

Answer 1

Tangent – radius theorem.

Explanation:

Because it states that the tangent at any point of a circle is perpendicular to the radius through the point of contact. When you construct a tangent using the center of the circle, you draw a radius to the point on the circle and then construct a line perpendicular to that radius at that specific point.
