A shape

He needs to draw a square

So it's basically a square????

Quadrangle is a plane figure consisting of four points, each of which is joined to two other points by a line segment; the line segments may intersect. Quadrangles can be concave or convex. If it is convex in shape it is called a quadrilateral.

Haha! I'm helping my brother with the exact same math problem! I don't get it either ..

My son has to draw a quadrangle and measure to the nearest 1/2 inch, what does it look like?

A quadrangle is basically a figure consisting of four points. Each point is connected to two other points with the help of line segments which may cross each other at some point. Please clink on this link to get further information and diagrams.
