Triangles are similar when their corresponding sides are in constant ratio

is 12/36 = 8/24   ?

anonymous · Answer

yeah but you cant find the ratio of the third side
would that make this triangle not similar

unklerhaukus · Answer

the third side can be found with Pythagorus

unklerhaukus · Answer

another test for similarity is if the angles in the triangle are all equal,

in this example , one angle is common, and both triangles have a right angle,

we know that the remaining θ must be   180°-90°-common angle
which will be the same

I know both triangles have right angles.. but what other angle do they have in common?
