When the given vertices are plotted and joined together on the Cartesian plane they will form a 4 sided quadrilateral whose diagonals intercept each other at right angles and so multiplying the lengths of the diagonals divided by two will produce an area of 80 square units.

How many edges and vertices are on a pyramid?
8 edges and 5 vertices. * * * * * Only if it is a quadrilateral based pyramid. A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.
Can you determine the number of triangles whose vertices are the vertices of an octagon but none of whose sides happen to come from the octagon?
I bilieve the answer is 16.
Are squares regular quadrilaterals?
Yes it is a square is a regular quadrilateral because it is not a unknown shape * * * * * That is an interesting reason - but wrong. A square is the only quadrilateral whose sides are all equal and whose angles are all equal. Both sides and angles must be equal for a polygon to be termed regular.
Quadrilateral formed by connecting the midpoints of consecutive sides?
A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
What is a polygon whose vertices are on a circle and has both endpoints on the circle?
star
What are supplementary angles that are NOT a linear pair?
Any two angles whose measures add up to 180 degrees. For example, opposite angles of a cyclic quadrilateral (quadrilateral whose vertices are on a circle).
How many vertices have a pyramid?
A pyramid, whose base is a polygon with n sides, has n+1 vertices. Thus a triangular pyramid (tetrahedron) has 4 vertices, a quadrilateral (square or rectangular) pyramid has 5 vertices; etc.
Does a parallelogram have a 90 degree angle?
No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
Where did the name rectangle come from?
It is a quadrilateral, all of whose vertices are right angles. Recht = German for right so rechtangle -> rectangle.

What is the most precise name for quadrilateral ABCD with vertices A(5 2) B(5 2) C(0 2) and D(0 2)?
From the given coordinates it would form a line segment whose end points are (5, 2) and (0, 2) and so there is no 4 sided quadrilateral.
Is a kind of quadrilateral one of whose angles has an interior point which is not in the interior of the quadrilaterals?
A concave quadrilateral
A polygon whose vertices are on the circle and whose edges are within the is an?
An inscribed polygon
A polygon whose vertices lie on a circle?
triangle
What is a Quadrilateral whose opposite angles are equal?
rhombus
