MATH 202 Chapter Notes - Chapter 10: Parallel Postulate
Document Summary
10. 1 lines and angles: angles can represent an amount of rotation or region formed between two rays that meet, there are three important relationships concerning angles produced by configurations of lines. When two lines meet, the angles opposite each other are equal. When two parallel lines are cut by a third line, the corresponding angles that are produced are equal; this is called the parallel postulate: three lines can meet to form a triangle. The angles in a triangle add to 180 . 10. 2 angles and phenomena in the world: angles arise in real-world situations. Angles are formed by the sun"s rays and angles descried reflected light rays. 10. 4 triangles, quadrilaterals, and other polygons: squares, rectangles, parallelograms, rhombuses, and trapezoids are special kinds of quadrilaterals.
