hartnn (hartnn):
then they are already similar, what to make ?
do u need to prove something ?
OpenStudy (anonymous):
i mean how to prove them simialr and what condition comes when they are similar
OpenStudy (anonymous):
angle A =angle A(common)
B=B (90 degree)
thus traingles are similar
OpenStudy (jhannybean):
create a ratio of triangle measures..
hartnn (hartnn):
B=B, no....
and i would write the names properly,
angle BAC = angle BAD (common angle)
angle ABC = angle ADB(both 90 degrees)
