Are the figures below similar? Explain

Answer:
No
Step-by-step explanation:
Similar shapes are shapes which have the same ratio between the sides.
If you can either increase or decrease the size of one shape to make it equivalent to the other shape, the two shapes are similar.
In your example, we cannot change the size of the left-hand shape to make it equal to the right-hand shape.
Thus, the shapes are not similar.
