Determine whether the pair of figures is similar or not. Explain your reasoning.
Rectangle DEFG is shown with side DE labeled 15, side EF labeled 8, side FG labeled 15, and side GD labeled 8. Rectangle WXYZ is shown with side WX labeled 7.5, side XY labeled 4, side YZ labeled 7.5, and side ZW labeled 4.
No, the shapes are not similar because they are different sizes.
Yes, they are similar because they are both rectangles.
Yes, they are similar because they have proportional side lengths and equal angle measures.
No, they are not similar because we don’t know the measures of their angles.
