Practice
Answer each of the questions based on what you learned on the last page. You can use the diagram to help you, if you would like.
Circle With 2 Tangents
Angle
What kind of angle is ?
Segments
Which statements are true? (Select all that are true.)
Sement Measure
If DB = 7, what is the length of DC?
Segment - Algebraic
If DB = 2x - 5 and DC = x + 8, find the measure of x and the length of DC. (Select both from the list.)
Triangle
What kind of triangle are triangles ACD and ABD? What does this tell us we can use for side lengths?
Missing Segment
If circle A has a radius of 10 and DB = 19, how far is the center of the circle from where the two tangent lines intersect? Rephrased: what is the length of DA? (Look at the question above for a hint.)
