Buttons take you to another slide where visuals are displayed. TC (Theorems Cont.) This slide is a continuation of the previous theorems slide.īD (Basic Definitions) Four definitions are given. Click the theorem to take you to another slide where examples are presented. T (Theorems) The first six theorems of the chapter are given along with their definitions. Click the postulate to take you to another slide where examples are presented. P (Postulates) The first three of the chapter are given along with their definitions. Helppp!! BI T ✪ TC P BD R Q QI H Qui-zlet Ask peers Read through book Look on YouTube or Khan Academy Come see me before or after school Click the buttons around the slide for a description of each of the sections of the PowerPoint (they are abbreviated).īI (Background Info) This slide explains the definitions of theorems and postulates. It only takes 1 to force the class to answer more.
After the 5, students can raise their hands if they wish to continue with the quiz. If the definition is drawn, the name must be written. If the name or part of the definition is drawn, the definition must be written (Pretty close to word-for-word). From there, you and your classmates will come to the front and choose one from the cup. A mixture of the names and definitions will be placed in a cup. Quiz Info Out of the 13 definitions only 5 will be on the quiz tomorrow.

Theorems NOTE: Click each theorem to take you to another slide with examples If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular If two sides of two adjacent acute angles are perpendicular, then the angles are complementary If two lines are perpendicular, then they intersect to form four right angles A postulate is a statement that is accepted without proof and is fundamental to a subject A theorem is a logical argument in the sense that if a hypothesis is true then the conclusion must also be true. A theorem is a proof of the truth of the resulting expression.
