Yes
Yes, they do.
They are either kites or (if the diagonals bisect each other) rhombuses.
They are a square, a rhombus and a kite.
Most quadrilaterals will satisfy that requirement. Those that do (squares and kites) are the exception.
Kites are 4 sided quadrilaterals Kites adjacent sides are equal Kites have I pair of opposite angles that are equal Kites have 4 interior angles that add up to 360 degrees Kites have 2 diagonals that bisect each other at 90 degrees
The diagonals of a square and a rhombus cross at right angles.
The diagonals of a rectangle do not cross at right angles
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.
Kite* * * * *No. On two counts:Only one of the diagonals is bisected.They meet at right angles.The correct answer is a parallelogram.
No but the diagonals of a square intersect at right angles
Well, honey, that would be rectangles. Those four-sided figures have diagonals that are equal in length and intersect at right angles outside the shape. So, if you're looking for a shape with some perpendicular diagonal action, rectangles are where it's at.
Oh, dude, no way! Diagonals of a trapezium definitely don't cross at right angles. They're like rebels, crossing all nonchalantly at different angles, not conforming to any right angle rules. It's like they're saying, "We're diagonals, we do what we want!"
