An Angle is a figure formed by two rays with a common endpoint, called the . vertex. .. vertex. ray. ray. Angles can have points in the interior, in the exterior or on the angle.. Mr. Peterson. CC standard 7.g.5. Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to . write and solve simples equations for an unknown angle in a figure. . Definitions. Complementary angles – the sum of their measures is 90˚. Each angle is the compliment of the other. A. B. 32˚. 58˚. Definitions. Supplementary angles – the sum of their measures is 180˚.

Using your Protractor. Chapter 6.1. Angles are formed by two rays that have a common endpoint (vertex).. The first ray you draw is called the initial side.. The second ray you draw is called the terminal side.. Initial Side. Protractor: . What do you notice? . Task One: . Look at the protractor. Write down everything that you notice about the protractor. Try and come up with at least . 10 facts. Think about . number patterns . Vocabulary. Complimentary Angles – When two angles add up to 90°. Supplementary Angles – When two angles add up to 180°. Using Complimentary & Supplementary Angles. Vocabulary Review. Acute Angle. Concept 1. Find the Interior Angles Sum of a Polygon. A. . Find the sum of . the measures . of the interior angles of a convex nonagon.. A nonagon has nine sides. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures.. The vertical distance from rotary table to Point B is called a true vertical depth. The inclination angle ‘I’ is the angle between vertical and the wellbore. . The direction angle ‘A’ is specified as the azimuth between the geographic north and the projection of a wellbore on a horizontal plane.. Hyonoo Joo, BS. 1. Deepa . Galaiya. , MD. 1. 1.
