A rectangle, square or isosceles trapezium.
A square.
Yes and the diagonals are not equal in length
A parallelogram.
It is a square because its diagonals are equal in length and they bisect each other at right angles which is 90 degrees The diagonals of a rhombus are not equal in length but they meet at right angles.
A square and a rectangle
A Quadrilateral has two diagonals. IF the quadrilateral is a rectangle, then the two diagonals are equal in length.
A square.
rhombus
It is an isosceles trapezoid.
A rectangle, a square, and an isosceles trapezoid.
Yes and the diagonals are not equal in length
trapezium
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 parallelogram.
A rectangle (or square), isosceles trapezium and some kites.
The quadrilateral you are referring to is called a kite. A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length, and one pair of diagonals that are not equal in length. Additionally, a kite has two axes of symmetry, which are lines that divide the kite into two congruent halves.
A rhombus
