1. 1.7 Bisecting Segments and Angles Warm-up (IN) Learning Objective: to identify bisectors and find real world distances and angle measures. 1. Suppose MN=28 cm. Find EN. 2. Name an angle that is congruent to 14 MEN G H I J K L

2. Bisector of a segment - Notes Line, ray, segment or plane that intersects a segment at its midpt Midpoint of a segment - MEN N CA B Y

3. C A B D Ex 1 - Find n F E B A 5n-1 14 EB=BF 5n-1=14 5n=15 n=3

4. Angle bisector - L O N M

5. Ex 2 - W P R Q Construct the midpointmidpoint Construct the angle bisectorangle bisector

6. HW – p. 44-47 #1-22, 29-32, 35-39 Out – How does the definition of an angle bisector compare to the definition of a segment bisector? Summary – I understand… Or I have more questions about… Challenge Probs. For EC…
