What is the purpose of drawing a line segment joining the centers of the circles?
To test if the common tangent intersects the segment.
To determine if the circles are tangent internally or tangent externally.
To check if the circles are round.
To classify the line segment as tangent line.
A tangent line XY touches the circle A at point B and formed the radius AB. Is it true that the radius AB perpendicular to the tangent line XY?
Yes, the radius is perpendicular to the tangent line.
Yes, the tangent line is the radius of the circle.
No, the radius is not perpendicular to the tangent line.
No, the radius of the circle is secant and tangent to the circle.
What do you called the point of intersection between the circle and a tangent line?
Point of Reference
Point of Sale
Point of View
Point of Tangency
How do you know if a line is tangent to a circle?
When it is parallel to the circle.
When it pass through to the center of the circle.
When it touches the circle in exactly two point.
When it touches the circle in exactly one point.
