Given: ∠ ABC and Angle Pair Relationships Date_____ Period____ Name the relationship: complementary, linear pair, vertical, or adjacent) a b linear pair 2) a b adjacent 3) a b adjacent 4) a b Using Trigonometry to Find Angle Measures Date_____ Period____ Find each angle measure to the nearest degree) tan A =° 2) cos Z =° 3) tan Y = Warm-Up Angle Relationships Lesson Goals Use the relationships to find unknown angle. Mention parallel lines and write and solve an equation when needed. Identify relationships. Recognize vertical angles to find each measure. Find the measure of each angle and name a relationship you used to find the measure. Warm Up: Use the diagram below to list all the pairs of vertical angles. If the measure of <1 =and the measure of <6 =, then find the measure of all the other six(6) angles Angle Pair Relationships Date_____ Period____ Name the relationship: complementary, linear pair, vertical, or adjacent) a b linear pair 2) a b adjacent 3) a b adjacent 4) a b complementary 5) a b vertical 6) a b adjacent 7) a b linear pair 8) a b vertical Find the measure of angle b) b° °)° b°) °° b° Students describe the angle relationship in the question and set up and solve an equation that models it. Key Vocabulary Complementary and Set up and solve an equation for the unknown angle based on the relevant angle relationships in the diagram. Students must have an understanding of vertical angles, complementary angles, supplementary Proving Angle Relationships. Any adjacent angle pair are on a line and sum to Objective: practice finding missing angle measures using angle relationships. Construct a chord in a circle. Use dynamic geometry software. Angle relationships worksheet helps kids to learn different types of angles including Finding angle measures between intersecting lines Getofquestions to level up! At one of the endpoints of the chord, construct a tangent line to the circle. Exploring Angle Pairs Students will be able to: Identify Special Angle Pairs and use their relationships to find angle measures. Find the measures of the two angles formed by the chord and the tangent line Here are more angle relationships shown in this figureName other pairs of corresponding angles, alternate interior angles, vertical angles, and angles in a linear pair. Have students verify their answers by measuring the unknown angle with a protractor This lesson will require you to use these different pieces of information to find angle measures, show triangles to be similar to one another and make mathematical connections. Recognize alternate interior angles to find each measure Angles: Finding measures of unknown angles by using relationships (use your notes). Words to Know Fill in this table as you work through the Students can identify adjacent, complementary, linear pairs, or vertical angles. Work with a partner. Based on the following figure, which angle relationship(s) can be utilized to find the measure of an obtuse and acute angle? Use the angle numbers () to list of the vertical angles. Add labels to diagrams as needed to facilitate their solutionsAim: I can determine what angle relationships exist when a parallel line is cut by a transversal. REMEMBER: Reasons can ONLY include relationships to angles that are already known This graphic organizer describes the relationships of interior and exterior angles in a triangle. The exterior angle of a triangle is an angle formed by a side and an extension of the adjacent side Angles Formed by a Chord and Tangent Line. The following theorems hold true for angles and can be used in proofs dealing with angles. Use the given information to find the measures of the angles Example: Write a two-column proof.
