Question

Are the triangles similar? How do you know?
A. yes, by SAS

B. yes, by SSS

C. yes, by AA

D. no

Answer 1

sum of two angles of first triangle=84.6+30.4=115.0
third angle=180-115=65
i think now you can find the solution.

Answer 2

similar triangles have the same 3 angles

so find the 3rd angle in each triangle (using the fact that all 3 add up to 180 degrees)

if both triangles have the same 3 angles, they are similar

Answer 3

@phi sorry @surjithayer confused me

Answer 4

ah ha nevermind they arent similar

Answer 5

they are not similar because 66 is not in the first triangle
