Chapter 1. Angles and Segments Study Guide Target 1A. Segment and Angle Addition Postulates. I can use Segment and Angle Addition Postulates, midpoints, and bisectors to find segment lengths and angle measures. 1 I can apply Segment Addition Postulate to calculate segment lengths. I can use the concept of midpoint to calculate segment lengths. I can apply Angle Addition Postulate to calculate angle measures. I can use the concept of bisector to calculate angle measures. m∠KJI = 120° and m∠CJI = 100° a) Find m∠KJC. b) What postulate did you use to solve this problem? EF = 3x + 5, FG = 5x - 10, and EG = 21 Solve for x. Find HJ. m∠HFG = 2x + 6 Find m∠XYW if m∠2 = 22x and m∠1 = 24x - 2 and PY bisects ∠XYW. m∠2 = 22x m∠1 = 24x - 2 T is the midpoint of SU, ST = 3x - 10, and TU = 2x + 7. Find TU. ST = 3x - 10 TU = 2x + 7 Find RS. RS = 2x - 3 m∠ABC = 3x + 8; m∠CBD = 2x + 7 Solve for x. If FG = 3, GH = 3, HJ = 5, and IK = 11, explain how you would determine GK using the segment addition postulate. GK = 6; H = 3 + 5 + 11 = 19 Target 1B. Midpoint and Distance Formulas. I can calculate the distance between two points on the Coordinate Plane & the midpoint between two points on the Coordinate Plane. 1 I can calculate the distance between two points on a coordinate plane. I can calculate the coordinates of a midpoint on a coordinate plane. I can calculate determine areas and perimeters of polygons on a coordinate plane. For each graph, find: a) the length of the segment b) the coordinates of the midpoint. (You will have 2 answers per problem) [Graphs and Calculations for Distance and Midpoint] Find the other endpoint, point "B", given endpoint "A" and midpoint "M".
