What is a quadrangle?

• A. Four sided figure
• B. Circle
• C. Triangle
• D. Rectangle with curved sides

Answer: (A)

A quadrangle is a four-sided figure. In geometry, shapes with straight sides are called polygons, and the number of sides names the type. Four sides and four corners define a quadrangle (also called a quadrilateral), and it can take many forms—square, rectangle, trapezoid, etc.—as long as all sides are straight. The interior angles of any simple quadrangle add up to 360 degrees. The other options describe shapes that don’t fit four straight sides: a circle has no sides, a triangle has three, and a rectangle with curved sides isn’t a polygon at all. So the four-sided figure is the correct description.
