proof Proof Logical statement that shows a statement is true Twocolumn proof Statements amp corresponding reasons that show an argument in a logical order Review example. Customer segments:. Low-end (students). Fun to build. Flexibility. High-end interior design. Customize-ability. Flexibility. Commercial (office design). Modularity. Flexibility. Value proposition:. Talk to people. Angles are ACUTE angles Angles equal to 90 are RIGHT angles Angle are OBTUSE angles Angles equal to 180 Angles more than 180 are REFLEX angles Two Angles are Complementary if . and only if they . add up to 90 degrees (a Right Angle).. Definition of Complementary Angles. They don't have to be next to each other, just so long as the total is 90 degrees.. Ms. Andrejko. Vocabulary. Included side-. the side located between two consecutive interior angles of a polygon. Real-World. Postulates/Theorems/Corollaries. P 4.3:. If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. Postulates. Postulate: a rule that is accepted without proof. Theorem: a rule that can be proved. Postulate 1 – Ruler Postulate. . The points on a line can be matched one to one with the real numbers. The real number that corresponds to a point is he coordinate of the point.. Look for the similar Triangles. Parallel Lines and Transversal. Alternate interior angles are congruent if the lines are parallel. Corresponding angles are congruent if the lines are parallel. Could use SSI to prove lines parallel. Theorems are statements that can be proved. Theorem 2.1 Properties of Segment Congruence. Reflexive AB . ≌. AB . All shapes are . ≌. to them self. Symmetric If AB . ≌. CD, then CD . ≌. AB. Measuring Segments. Students will be able . to:. Measure . and compare lengths of . segments using ruler. . . . Key Vocabulary. Line Segment. Distance/length. congruent segments. Segment bisector. Chapter 4. Objective. List corresponding parts.. Prove triangles congruent (ASA, SAS, AAS, SSS, HL). Prove corresponding parts congruent (CPCTC). Examine overlapping triangles.. Key Vocabulary - Review. Lesson 2.5. In the diagram above, AB = CD.. Do you think that AC = BD?. Suppose that BC were 3cm. Would AC = BD?. If AB = CD, does the length of BC have any effect on whether . AC = BD?. A. C. B. D. Common Core Investigation 4: Geometry Topics. 4. 3. 2. 1. 0.
