Geometry Chapter 10 Part 2 Review Study this review and you should do well on the exam. Don’t forget all the terms you learned from the first half of this chapter. Don’t forget to make yourself a note card. Vocabulary to know: circumscribed polygon point of tangency tangent line perimeter secant line Skills to Hone and Practice Problems: In all practice problems assume all lines or segments that look tangent are tangent. Section 10.5: Know what a tangent line is and know the relationship between a tangent line and a radius drawn to the point of tangency. Know the relationship between two segments that are tangent to a circle from the same point of tangency outside the circle. Practice problem 1: Given circle P with A being the point of tangency, find AN. Find the exact value and approximate to the nearest hundredth. Practice problem 2: Given AR = 52, AD = 18, TX = 12. Find the perimeter of ART Practice Problem 3: Find the value of x. Section 10.6: Know how to find the measures of angles created when two secants intersect inside a circle. Know how to find the measures of angles created when a secant and a tangent intersect at the point of tangency. Know how to find the measures of angles created when secants and/or tangents intersect outside a circle. Practice Problem 4: Find x in each diagram. The given arc or angle measures are in degrees. Practice Problem 5: Given circle E with CG tangent at point C, mAB=50, DH=75, mHC=30, and diameter BD. Find mABD, mAFB, mCGD. Section 10.7: Know how to find the length of segments formed when secants and/or tangents intersect. Practice Problem 6: Find x in each of the diagrams. Assume segments that look tangent are. **Study**Study**Study**Study**Study**Study**Study**Study**Study**Study**
