|
|
|
|
This worksheet contains problems on circles and tangent lines. Problems require an understanding and applicatoin of the theorems and properties of tangents.
There are also problems on circumscribed and inscribed circles and polygons.

Sample Problems from Worksheet (diagrams not shown) |
|
1) Assume that lines that appear to be tangent are tangent. O is the center of the
circle. Find the value of x.
3) Determine whether a tangent line is shown in the diagram. Explain.
6) AB is tangent to circle O at B. Find the length of the radius r. Round to the nearest tenth if necessary.
7) Tell whether the polygon is inscribed in or circumscribed about the circle.
9) In triangle NML, NL = NM, and the perimeter is 46 cm. A, B, and C are points
of tangency to the circle. MC = 6 cm. Find the length of NL. Show your reasoning.
