Need help with geometry. Proving one triangle is similar to another.

OpenStudy (threshsupport):

yay finally help...

OpenStudy (threshsupport):

i know 2 and 3 need help with part 1

OpenStudy (threshsupport):

ok then

OpenStudy (threshsupport):

OpenStudy (threshsupport):

i know that they are vertical angles and they are equal

myininaya (myininaya):

ok but you skipping number 2

myininaya (myininaya):

yes angle ABC is congruent to angle DBE since we know vertical angles are congurent

OpenStudy (threshsupport):

yea because i dont know the theorem for part 2

myininaya (myininaya):

step 2 also tells us something about the sides

myininaya (myininaya):
