Name _________________________________________________ Unit 1 Overview/Review Projected Test Date: September 5 -use the basic defined and undefined terms of geometry. -use the segment postulates. -solve problems involving midpoint and bisectors. Given: C is the midpoint of AD AD = 17 A B D C Determine the length of AB -use the basic defined and undefined terms of geometry. -identify complementary and supplementary angles. -solve problems involving vertical angles, linear pairs, complementary and supplementary angles. What is the complement to a 37˚ angle? -use the basic defined and undefined terms of geometry. (Notation) -classify angles as acute, right, obtuse or straight. Give the acceptable notation for the given angle. (there are four) Classify the given angle. G O 1 D -use the basic defined and undefined terms of geometry. -classify angles as acute, right, obtuse or straight. The degree measure of A is three times the measure of B , its supplement. Find the measure of A . -solve problems involving midpoint and bisectors. The midpoint of BC is M(5, -6). One endpoint is B(-1, 8). What are the coordinates of C? -use the basic defined and undefined terms of geometry. C B A G F E H Name the intersection of AEF and FGH. Name the intersection of CD and AD . -use the basic defined and undefined terms of geometry. Write the correct notation for a line through points A and B. Write the correct notation for a ray from A through B. Write the correct notation for a line segment with endpoints A and B. Write the notation for the length of the segment between A and B. -use the basic defined and undefined terms of geometry. -use the segment postulates. Let B be between A and C. Use the Segment Addition Postulate to find AB. AB = 5w - 12 BC = 4w - 9 AC = 39 -use the distance formula appropriately. On a certain farm, individual crops are laid out in rectangles that are 60 feet north and south, and 40 feet east and west. How far would you have to walk to get from the shed (S) to the well (W) if you did not step on any crops? How far would it be if you walked diagonally across the crops? 180 S –200 200 –180 W -use the basic defined and undefined terms of geometry. -use angle postulates. -solve problems involving midpoint and bisectors. If QS bisects PQR , find the measure of PQR . P (4 x 6) S (2 x 12) R Q -identify -solve linear pairs, Solve for x: vertical angles. problems involving vertical angles, complementary and supplementary angles. 3x + 20 4x + 16 -identify linear pairs. -identify complementary and supplementary angles. -solve problems involving vertical angles, linear pairs, complementary and supplementary angles. Find mBAC E D 3 x + 136 3x + 26 A B C -use a ruler to measure segments. -use a protractor to measure angles. Use an appropriate tool to find the measure of the given angle. Then use an appropriate tool to find the length of segment AB, give your answer in two different units. A B
