(d)Using your knowledge of circles, label the following on the given diagram: chord, tangent, radius, secant, point of tangency and diameter. Name a minor arc and a major arc.

The top is Tangent

The blue line is Radius

The red line is Diameter

I'm not sure on the rest

A *chord* is any line segment that has endpoints on the circle.

On the diagram, \(\color{gray}\overline{AC}\) is a chord and \(\color{limegreen}\overline{BD}\) is a chord.

A *tangent* line is a line that touches the circle at exactly one point.

On the diagram, the top line is a tangent line.

A *radius* is a line segment that has one endpoint on the circle and one endpoint at the circle's center.

All points on a circle are the same distance away from the center. That distance is the radius's length.

On the diagram, the red line segment is a radius.

A *secant* is a line that passes through the circle, touching the circle at two points.

On the diagram, the blue line is a secant line.

Remember that a tangent line is a line that touches the circle at exactly one point.

Its *point of tangency* is that point.

On the diagram, the yellow point is a point of tangency.

A *diameter *is a chord that goes through the center of the circle.

On the diagram, \(\color{limegreen}\overline{BD}\) is a diameter.

An example of a minor arc is \(\stackrel{\,\frown}{AB}\)

An example of a major arc is \(\stackrel{\,\frown}{ADB}\)
