The problem asks which two shapes are similar. Two shapes are considered similar if they have the same shape but possibly different sizes, meaning their corresponding angles are equal and their corresponding sides are proportional.

Let's analyze the shapes visually:

• Shape A and Shape D both appear to have similar trapezoid structures but are clearly not proportional.
• Shape B and Shape E are both trapezoids and appear to have the same angle structure and a proportional side length ratio, so these two are likely similar.
• Shape C and Shape F are triangles but are not proportional or congruent to each other.

Thus, shapes B and E are similar.

Would you like a deeper explanation on how to determine similarity or have further questions?

Here are 5 related questions:

1. How do you calculate the scale factor between two similar shapes?
2. What is the difference between similar and congruent shapes?
3. Can two different shapes be similar if they have proportional sides?
4. How can you prove that two triangles are similar?
5. What role do angles play in determining similarity?

Tip: Always check both the angles and the ratios of corresponding sides to confirm similarity.
