1 Warm- Up 1.What is the coordinate for the midpoint AC 2.Calculate the distance of CD 3.What coordinate point is 5 units from C

2 Homework

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

4 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

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

6 Angle Addition Postulate TOTAL = PARTS
