Well, last class we basically spent the whole class correcting the homework from the day before, which was page 373-374 #12-29.
12) Green:







I divided the small triangle by the big oneto discover x. The first equation solves for segment FB,which is 4, then the next one solves for DC which is also 4.
15) Blue:
you can see that DB is the median of EC and AC, and by using logical reasoning one can tell that its also the median of GC, so by knowing GF is 18, you know that FC is also 18.
13) Orange:
you can discover it the same way as 15 or by dividing side by side equals altitude divided by altitude.

19) Theorem 7-11 stats that:



29) to discover CF:
because of theorem 7-11

and to discover BD :

Ms. Saatkamp also let us work on the new homework she assigned as a review for the quiz on Monday. The review is:page 388 #13-30.
#27-30 are what will fall on monday´s quiz.
