State weather the following quadrilaterals are similar or not

Step 1: Investigate the given figures and compare the measurements
Step 2: Recall the definition of the similar figures
DEFINITION: Two figures are similar means that they share a common
shape. They can be different sizes, but they must have the same shape.
Step 3: Make sure that the given figures are satisfying the definition of similar figures or not.
NOTE: Similar polygons have the same shape, but can be different sizes. Specifically, two polygons are similar if two things are true:
So when you take a square and compare it with another square, all sides of 1st one are proportional to another. And all angles are of course 90 degrees.
EXAMPLE: The given Figures are not similar because there corresponding angles are not equal.
