I got similarity cannot be determined

cwrw238 · Answer

no the 2 triangles are similar
because the two angles other than the rift angle are both 34 and 56 degrees

cwrw238 · Answer

i've never seen these postulates before but i guess it must be the angle-angle one

anonymous · Answer

@cwrw238 Yeah I was thinking angle-angle too but I wasn't sure, thanks!

we don't use that system in UK - well when i did geometry we didn't
