(Day 2) 70º, acute 90º, right 120º, obtuse Theorem #4: : 2 Geometry Lesson: Angle Theorems (Day 2) Theorem #4: If two angles are straight angles, then they are congruent. Def: : 3 Geometry Lesson: Angle Theorems (Day 2) Def: Def: Supplementary Angles are two angles whose measures add up to 180 degrees. Ex: Supplementary Angles : 4 Geometry Lesson: Angle Theorems (Day 2) Ex: Supplementary Angles 50º 96 º Def: : 5 Geometry Lesson: Angle Theorems (Day 2) Def: Def: A Linear Pair of angles is two adjacent angles whose union is a straight angle. Theorem #5: A linear pair of angles is supplementary. Ex: Supplementary Angles Proof : 6 Geometry Lesson: Angle Theorems (Day 2) Ex: Supplementary Angles Proof Given Given Def. suppl. angles Def. suppl. angles Substitution Postulate Reflexive Postulate Subtraction Postulate Theorems #6: : 7 Geometry Lesson: Angle Theorems (Day 2) Theorems #6: Theorem #6: Supplements of the same angle, or congruent angles, are congruent. Ex: Suppl. Angles Proof : 8 Geometry Lesson: Angle Theorems (Day 2) Ex: Suppl. Angles Proof Given Supplements of the same, or congruent angles, are congruent. Def. Of linear pair A linear pair of angles is supplementary. Def: : 9 Geometry Lesson: Angle Theorems (Day 2) Def: Def: A Vertical Pair of angles is two angles in which the sides of one angle are opposite rays to the sides of the other angle. Theorem #7: Vertical angles are congruent. Ex 1,2,3: Compl./Suppl./Vert. Angles: : 10 Geometry Lesson: Angle Theorems (Day 2) Ex 1,2,3: Compl./Suppl./Vert. Angles: Ex 4, 5: Suppl. Angles : 11 Geometry Lesson: Angle Theorems (Day 2) Ex 4, 5: Suppl. Angles 4) Two supplementary angles have measures in the ratio 2:7. Determine the measure of both angles. 5) The measure of an angle is 20 less than 4 times its supplement. Find the measure of the angle and its supplement.
