Trapezoid problems require specifying the type of problem and difficulty level. To provide detailed examples, I need more information. Please specify:

1. Specific Trapezoid Properties to Focus On: Are the problems focused on area, perimeter, finding missing sides/angles (using properties like isosceles trapezoids, parallel sides, etc.), or other properties?

2. Difficulty Level: Easy problems might involve direct application of area/perimeter formulas with given values. Medium problems might require solving for a missing side or angle using properties of trapezoids and other geometric principles (e.g., Pythagorean theorem, similar triangles). Hard problems might involve more complex geometric proofs or applications involving coordinate geometry.

3. Number of Problems: How many problems are needed?

4. Problem Format: Do you prefer multiple-choice, open-ended (show your work), or a mix?

5. Specific Constraints (Optional): Are there any specific values or relationships between sides/angles that should be included in the problems? For example, should all trapezoids be isosceles? Should certain angles be specified?

Once this information is provided, I can generate detailed trapezoid math problems.
