(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   \(\stackrel{\,\frown}{ADB}\)
