1 Geometry Course Summary Department: Math Semester 1 Learning Objective #1 Geometry Basics Targets to Meet Learning Objective #1 Use inductive reasoning to make conclusions about mathematical patterns Give the appropriate notation for line, segment, ray, and angle. Draw representations of given geometric situations Determine whether points are collinear or coplanar Determine the distance or length of any segment given the coordinates of its endpoints Use the segment addition postulate to determine the length of segments that are separated into two or more segments Classify angles into groups according to the measure of their angles Use angle addition postulate to determine the measure of angles that are separated into two or more angles Use the midpoint formula to find the midpoint between two given endpoints Find one endpoint given the other endpoint and the midpoint Tell the difference between intersect and bisect Identify vertical angles and linear pairs. Find missing measurements using the fact that vertical angles are equal and linear pairs = 180 Find missing measures using the ideas of complementary and supplementary Find perimeter of any basic figure Use area formulas for triangle, rectangle, square, and circle Find a missing measurement given the area Learning Objective #2 Geometric Thinking Targets to Meet Learning Objective #2 Write conditional statements in if-then form Label parts of conditional statement Write converse, inverse, and contrapositive Write biconditional statements if the properties for a biconditional statement exist Use law of detachment and syllogism to make conjectures from other statements Use inductive and deductive reasoning to make conjectures about given information Use the algebraic properties of equality to solve equations and give a proof Write a two-column proof for segment theorems Write a two-column proof for angle theorems 7 blocks
