Question

Select the reason why these triangles are

similar. If they are not, select "Not similar".
A. AA
B. SAS
C. SSS
D. Not similar

Answer 1

B. SAS

Explanation:

In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of
`(1)/(3)` to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.

Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.
