a quadrilateral has 4 (quad) sides. a square is a quadrilateral.
Quadrilaterals usually have special names only if they DO have parallel sides, or some other special property. You might just call it "quadrilateral", or "a quadrilateral with no parallel sides".
A quadrilateral is inscribed in a circle it means all the vertices of quadrilateral are touching the circle. therefore it is a cyclic quadrilateral and sum of the opposite angles in cyclic quadrilateral is supplementary. suppose if one angle is A then another will be 180 degree - angle A.
Some trapezoids, not all.
Yes.
When you add all four sides of a quadrilateral(all parallelograms are quadrilateral), It must equal 360 degrees. So what you do is you add up the three angles that are given, them subtract that sum from 360.
All the names to classify a trapezoid are a trapezoid and a quadrilateral.
quadrilateral, parallelogram
a rectangle and quadrilateral
The best names, square, parallelogram and that is all I know. I hope i helped.
Parrallelogram, quadrilateral, square... PLEASE ADD
A parallelogram is a 4 sided quadrilateral.
A square is a quadrilateral with four equal sides and four right angles. It is also known as a regular quadrilateral or a regular tetragon. In geometry, a square can also be referred to as a rhombus (a quadrilateral with all sides of equal length) or a rectangle (a quadrilateral with opposite sides of equal length and all angles equal to 90 degrees).
Square and a rhombus * * * * * A rhombus is not a regular quadrilateral (unless it is a square) because being regular requires all sides AND all angles to be equal. So there is only one type of a regular quadrilateral - a square. It may have other names, certainly so in other languages.
Parallelogram, quadrilateral Parallelogram means "All opposite sides are equal" Quadrilateral means "Four-sided"
there are several names for rhombus quadrilaterals. rhombus quadrilateral is the main name of a rhombus quadrilateral. some other names arent very similar to this name but can still describe it.
they dont
a quadrilateral
