OpenStudy (***[isuru]***):

no

OpenStudy (***[isuru]***):

angles r not in the same size

OpenStudy (anonymous):

My bad misread. Isuru is right

OpenStudy (anonymous):

by SAS SSS SA

OpenStudy (***[isuru]***):

u only know 2 different angles in those 2 triangles... to become similar u need to know all 3 angles r equal

OpenStudy (anonymous):

not sa *AA

OpenStudy (***[isuru]***):

huh ?

OpenStudy (anonymous):

A. yes, by SAS B. yes, by SSS C. yes, by AA D. no

OpenStudy (***[isuru]***):

no

OpenStudy (anonymous):

The degree of measurment in a triangle is 180 degrees. To find the missing angle, you add the angles you know up and subtract that from 180. If they are the same it's similiar. I did my mental math wrong at first but isuru is right.

OpenStudy (***[isuru]***):

u can say the 2 triangles r similar if a = c and b = d

OpenStudy (***[isuru]***):

but in ur diagram only 84.6 is common for both triangles

OpenStudy (***[isuru]***):

with only that u cant say anything
