PPT-Lesson 1-4: Angles

1 Lesson 14 Angles Lesson 14 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. Essential Question. How can you describe angle pair relationships and use thee descriptions to find angle measures?. Objectives. Identify complementary and supplementary angles. Identify linear pairs and vertical angles. 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.. TOPIC/Objective: .

Adjacent and Vertical Angles. Lesson 7.1. Adjacent and Vertical Angles. Lesson 7.1. Adjacent and Vertical Angles. Lesson 7.1. Adjacent and Vertical Angles. Lesson 7.1. Adjacent and Vertical Angles. 1. Warm UP: . If. . m. . 1 = 23 º and m. . 2 = 32 º, find the measures of all other angles.. Answers:. Adjacent, . Vertical, . Supplementary, and Complementary Angles. Adjacent angles are “side by side” and share a common ray.. adjacent angles. complementary angles. supplementary angles. Congruent angles. have the same measure.. Vertical angles. are formed opposite each other when two lines intersect. Vertical angles have the same measure, so they are always congruent..
