Quadrilaterals
Quadrilaterals. A quadrilateral is a 2D shape with four sides.
What is a shape with 4 sides called?
Definition: A quadrilateral is a polygon with 4 sides. We name a quadrilateral by naming the four vertices in consecutive order. So we can name the quadrilateral as ABCD, or quadrilateral BCDA, or ADCB. Definition: A Trapezoid is a quadrilateral with a pair of parallel sides.
What is a 4 sided quadrilateral called?
(quad means four, lateral means side). A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides….The Trapezoid (UK: Trapezium)
