@hartnn

hartnn (hartnn):

if BD was perpendicular to AC, then those 2 triangles will be similar...

OpenStudy (anonymous):

yes , BD is perpendicualar to AC

OpenStudy (dan815):

do u mean AD*B is similar to ABC

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)

ganeshie8 (ganeshie8):

hartnn already proved it. two sets of Angles are equal. so AA similarity...

OpenStudy (jhannybean):

ok haha nvm!! :P

ganeshie8 (ganeshie8):
