Oh, dude, proving a quadrilateral is a trapezium is like proving your favorite Pizza topping is pepperoni - it's all about those parallel sides! If one pair of opposite sides of a quadrilateral are parallel, then you've got yourself a trapezium. It's as simple as that, like deciding between Netflix or Hulu for the night.

A quadrilateral can be proven to be a trapezium if it has at least one pair of parallel sides. This can be demonstrated by showing that one pair of opposite sides are parallel through various methods such as measuring the angles or sides, using the slope formula, or applying the midpoint theorem. Additionally, the consecutive angles between the parallel sides will add up to 180 degrees.

You can prove it if you can prove that one pair of opposite sides is parallel (and, strictly speaking, that the other pair is not).

Proving that the lines are parallel depends on the information available. Thier equations may have the same slope (gradient), or that the angles at their ends are supplementary, etc.
