Question

State if the triangles are similar. If so, state how you know they are similar and complete the similarity statement. If not, write "not similar"

Answer 1

First of all we need to remember that two triangles are similar if have two same angles. In the case of the image there are two similar angles between both triangles. I'm going to draw it:

Like you can see, you have two similar angles 90 and 61 degrees. Then both triangles are similar by AA.

Finally, the answer is the option A.
