right angled triangle does not have all equal sides
A square is a quadrilateral with four equal sides and four right angles.
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
Anything that has four sides is a quadrilateral.
right angled triangle does not have all equal sides
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
It's impossible for a quadrilateral to have no equal sides and have right angles.
A square is a quadrilateral with four equal sides and four right angles.
A quadrilateral with 4 equal sides and 4 right angles is a square.
The spelling rhombus is a four-sided shape (an angled square).It is a quadrilateral with four equal sides but no right angles.
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.

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.
a rectangle
