Answer 1

Answer: B

Step-by-step explanation: One is a triangle and one is not. The bigger one has four sides therefore it is not a triangle

Answer 2

B. Not similar

Explanation:

You want an appropriate choice of similarity reason for the triangles shown in the figure.

Side ratios

The side ratios in the smaller triangle are ...

0.5 : 1 : 1 = 1 : 2 : 2

The side ratios in the larger triangle are ...

2.25 : 3 : 3.5 = 9 : 12 : 14

The side ratios are not the same, so the triangles are not similar.
