Geometry plz help describe why or why not these are similar

These two triangles are similar because the sides are proportional to each-other. The constant of proportionality is 1.5. That means that each corresponding side (3:4.5, 2:3, and 4:6) from the smaller triangle to the bigger one can be multiplied by 1.5, which is why they're similar.

No

Step-by-step explanation:

These triangles are similar because of shape, however, In size they are different. The triangle on the right is 2.5 sizes bigger then the one on the left. Therefore, they are different and the correct answer is no.

Hope his helps :D
