Homework

Objective To find and Compare the Measures of angles – Define angles – Protractor Postulate – Congruent Angles (Tick Mark) – Angel Addition Postulate

Protractors Postulate 1-7…The measure of an angle is the absolute value of the difference of the real numbers paired with each “Ray” of the angle. = l c-d l

Types of angles Acute= <90° Right = 90° Obtuse = > 90° Straight = 180° Congruent Angles are equal with the tick mark

Angle Addition Postulate TOTAL = PARTS

Ex. Calculate Angles Angle ABC = 129° Find X Find Angle ABD Find Angle DBC
