PPT-1.4 Measure & Classify Angles

Angles amp Their Names Angle consists of two different rays with the same endpoint Sides the rays of the angle Vertex the endpoint of the angle Name the 3 angles or or or   Angles amp Their Measures. Recognising different types of angles. What type of angle is this?. Right angle. What type of angle is this?. acute. What type of angle is this?. obtuse. What type of angle is this?. acute. What type of angle is this?. 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. . 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 Central Angles. Central Angle. (of a circle). Central Angle. (of a circle). NOT A. Central Angle. (of a circle). A . central angle. is an angle whose vertex is the CENTER of the circle. CENTRAL ANGLES AND ARCS. 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. . 1. Lesson 1-4. Angles. Lesson 1-4: Angles. 2. Angle and Points. 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.. • Two rays with the same endpoint. • The rays are the sides . of the angle. .. • The common endpoint . of the 2 rays is the . vertex of the angle.. Name the sides and vertex of this angle:. 9.10.15. Do Now. Define the following:. Acute angle. Straight angle. Right angle. Obtuse angle. Ray. Line. Line segment. How do you prove you are right?. Proving You . A. re Right. We write an explanation of our thinking or thought process. 105 = 2x 5. . . 50. 2. . 119 – x = 3x 11. . 27. 3. . 2x . – 7 = -4x 1. .  . Linear Pair. I: Two angles that share a common vertex and together make a straight line (180°).. M: What is the missing measure?. 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..
