Since this polygon is inscribed within a circle, we know a few things.

The first thing we know is that the sum of all the interior angles must equal .

The last thing we know, the most important one is all opposite angles must equal .

Now we need to set up equations to solve for , and .

Now let's solve for , and .

To construct a line that is tangent to a point on the circle and passes through the origin, recall what it means for a line to be "tangent". A line that is tangent to a point on a circle means that the line will only touch the circle at that specific point.

Given the equation of the circle,

the center and radius of the circle can be determined.

The center is located at  and the radius is .

Therefore, the center is located at  and the radius is three. Plotting the circle and tangent line to the origin results in the following.

To construct a line that is tangent to a point on the circle and passes through the point outside the circle, recall what it means for a line to be "tangent". A line that is tangent to a point on a circle means that the line will only touch the circle at that specific point.

Using the plotted circle and the given point, two potential lines can be drawn that will touch the circle at one point. One possible line would touch the circle on the left half of the circumference while the other potential line would touch the circle on the right half.

Constructing a potential tangent line, a point can be plotted on the circle as follows.

From here, connect the given point outside the circle to the point on the circle with a straight line. Thus resulting in a tangent line to the circle.

To construct a line that is tangent to a point on the circle, recall what it means for a line to be "tangent". A line that is tangent to a point on a circle means that the line will only touch the circle at that specific point.

Looking at the image, it is seen that the line only touches the circle once therefore, the line is tangent to the circle. Thus this statement is true.

To construct a line that is tangent to a point on the circle, recall what it means for a line to be "tangent". A line that is tangent to a point on a circle means that the line will only touch the circle at that specific point.

Therefore, by definition the statement is false.

To construct a line that is tangent to a point on the circle, recall what it means for a line to be "tangent". A line that is tangent to a point on a circle means that the line will only touch the circle at that specific point.

Therefore, looking at the graph

it is seen that the line only intersects the circle once. Thus, the statement "The line is tangent to the circle." is true.
