Proving Quadrilaterals Given the four coordinates, draw a diagram of your quadrilateral. Then use distance formula and slope to determine which definition best fits your quadrilateral. After you have completed your calculations, write up your argument in a formal paragraph proof. A(1, -4), B(1, 1), C(-2, 2), D(-2, -3) Math Work: Proof/Argument:A quadrilateral is a mathematical name for a four-sided polygon. Parallelograms, squares, rectangles, and trapezoids are all examples of quadrilaterals. These quadrilaterals earn their distinction based on their properties, including the number of pairs of parallel sides they have and their angle and side measurements.Introduction to Proofs. Logic is a huge component of mathematics. Students are usually baptized into the world of logic when they take a course in geometry. However, there is plenty of logic being learned when studying algebra, the pre-cursor course to geometry.
