What is the definition of a secant?

• A line segment whose endpoints are on the circle.

• A line that intersects a circle in one point.

• A line that intersects a circle in two points.

• A line segment which intersects the circle at the point of secancy.

What is the definition of a tangent?

• A line that intersects the circle on two points.

• A line that passes through the center of the circle.

• A line segment that passes through the center of the circle.

• A line that intersects the circle on only one point.

Which is the correct equation to find m<KLM?

• x = 1/2(140 - 66)
• x = 1/2(140+66)
• 66 = 1/2(140 - x)
• 66 = 1/2(140 + x)
