Detailed FAQs

What is a quadrilateral in the coordinate plane?

A quadrilateral in the coordinate plane is a polygon with four sides and four vertices, where each vertex has coordinates (x, y) that specify its position on the plane.

How do I find the area of a quadrilateral in the coordinate plane?

To find the area of a quadrilateral in the coordinate plane, you can use the formula: Area = 1/2 – |(x1 – y2 + x2 – y3 + x3 – y4 + x4 – y1) – (x2 – y1 + x3 – y2 + x4 – y3 + x1 – y4)|, where (x1, y1), (x2, y2), (x3, y3), and (x4, y4) are the coordinates of the vertices.
