An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
A Rhombus * * * * * WRONG! A rhombus does not have equal diagonals. If it did it would be a square! The shape is a special case of a kite.
It's impossible for a quadrilateral to have no equal sides and have right angles.
square and rectangle * * * * * No. Square and Kite but NOT rectangle.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.

Two features of a rhombus are it is a quadrilateral shape because it has 4 sides which are equal in length and it has no corner right angles but its diagonals are perpendicular.
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
The diagonals of a rectangle do not cross at right angles
It will have 4 sides
A rectangle
yes 4 right angles
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
It is a rhombus. It is the only equilateral parallelogram other than a square, which conversely has all right angles.
NO quadrilateral has, except rectangles and squares.
Some of the properties of a square are as follows:- It's a 4 equal sided quadrilateral It has 4 equal interior right angles of 90 degrees Its interior angles add up to 360 degrees It has 2 equal diagonals that intercept each other at 90 degrees It has 4 lines of symmetry It will tessellate It can be split into triangles It has a perimeter which is the sum of its 4 sides It has an area which is its side squared
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
