Congruent Figures and Isosceles Triangles

2. Warm-Up
4. Which congruence postulate or theorem proves the triangles are congruent:

3. HW Check

4. Isosceles Triangles
s in which 2 or more sides are

5. If m<A=4x+2 and m<C=2x+20, Find x.

6. If m<B=x and m<A=2x+2, Find m<C.

7. 5-1 Midsegments of Triangles

9. ***Midsegment is parallel to the base (side it does not touch)

10. Midsegment = ½ * base OR Base = 2*Midsegment

11. Ex:1. H, J, K are midpoints a. What is the midsegment of EG:
b. What is the midsegment of FE:
c. What is the midsegment of FG:

12. d.

13. Ex. 2 Find x:

14. Ex. 3 Find x:

15. Ex. 4

17. We know AE = EB
