Question

Create a circle. Show and explain the difference between thefollowing:A. secant line and tangent lineb. inscribed angle and central angle

Answer 1

First, let's create a circle:

Then, let's explain what is a secant line and tangent line:

A)

A secant line is a line that intersects the circle in two points, and a tangent line is a line that intersects the circle in just one point:

B)

An inscribed angle is an angle that has the vertex as one point on the circle, and a central angle is an angle that has the vertex as the center of the circle:
