Alternate interior angles are congruent. Two lines are parallel if they have the same slope.

Answer 1

To determine what can be proved using a diagram, we need to consider the properties and theorems related to the elements depicted in the diagram. The following points can be proved based on typical geometric diagrams:

1. **The Pythagorean Theorem**: This can be proved if the diagram involves a right triangle, demonstrating that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

2. **The Triangle Angle Sum Theorem**: This can be demonstrated in any triangle, showing that the sum of the interior angles of a triangle equals 180 degrees.

3. **Alternate Interior Angles are Congruent**: This can be proved if the diagram shows two parallel lines cut by a transversal, indicating that the angles formed on opposite sides of the transversal are equal.

4. **Two Lines are Parallel if They Have the Same Slope**: While this statement is true in coordinate geometry, proving it would require a diagram that includes lines with defined slopes.

Without seeing the specific diagram, we cannot definitively choose which theorem can be proved. However, if the diagram involves a triangle, the Triangle Angle Sum Theorem is often a likely candidate. If it depicts parallel lines and a transversal, then proving that alternate interior angles are congruent could be possible.

In summary, depending on the diagram, any of the provided options could potentially be proven: the Pythagorean Theorem, the Triangle Angle Sum Theorem, alternate interior angles being congruent, or the parallelicity of lines based on slopes.
