#### A tangent is parallel to the radius through the point of contact.

A tangent is perpendicular to the radius through the point of contact.

#### A perpendicular to a tangent of a circle, at the point of contact passes through the centre of the circle.

A perpendicular to a tangent of a circle, at the point of contact passes through the centre of the circle.

#### What is the distance between two parallel tangents of a circle with diameter 16 cm?

The distance between the two parallel tangents is the diameter of a circle. Diameter = 16 cm Thus, the distance between two parallel tangents of the circle is 16 cm.

#### The angle between any tangent and radius at the point of contact of a circle is ____.

The tangent of a circle is perpendicular to the radius at the point of contact hence, the angle between a tangent and radius at the point of contact is 90°.

#### The angle between the tangent at a point on a circle and the radius at the point of contact is

It is known that the tangent at any point of a circle is perpendicular to the radius through the point of contact. Thus, the angle between the tangent at a point on a circle and the radius at the point of contact is 90^{o}

#### A line that intersects a circle in exactly one point is called a

A line that intersects a circle in exactly one point is called a tangent.

#### ____ tangents can be drawn to a circle from an external point.

Two tangents can be drawn to a circle from an external point.

#### Which of the following is incorrect?

RC and PB are not drawn from a common external point.

#### Any line touching a circle at only one point is called ____.

Any line touching a circle at only one point is called tangent.
