Question

The following triangles are similar. State the postulate or theorem that proves they are similar along with the correct scale factor. The diagram is not to scale.
a. SSS~; 3:4
b. SAS~; 1:3
c. SSS~; 1:3
d. SAS~; 3:4

Answer 1

I would have to say SAS because they give 2 sides and an angle. Also 3:4 because the one side is 3 and add 1 for 4, same for 30 and 40.
