because they have four sides, which is the definition of quadrilateral
A quadrilateral has four sides, and so four quadrilaterals will have a total of 16 sides counted separately.
The two quadrilaterals are squares.
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
No. A quadrilateral is a any closed polygon with four sides. A rectangle is a quadrilateral with four right angles and congruent opposing sides. Therefore, all rectangles are quadrilaterals, but not all quadrilaterals are rectangles.
Yes, all rectangles are quadrilaterals because they have four sides and all quadrilaterals have four sides.
They all have four sides.
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
Yes. Quadrilaterals means a closed shape with four sides, and a trapezoid has four sides, and is a closed shape.
Yes, the parallelograms are quadrilaterals because they have four sides.
Yes, all Quadrilaterals have four sides, therefore they must have 4 angles.
All quadrilaterals have four sides.
Shapes with four sides
No. A quadrilateral is any four-sided figure. The sides do not have to be of equal length, and the angles do not have to be right angles. So, all squares are quadrilaterals because they have four sides), but not all quadrilaterals are squares.
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
All quadrilaterals have four sides and four angles, as well as four vertices.
