Yes. It would be a rhombus.
A parallelogram.
rhombus
trapezoid
Parallelogram
No, a quadrilateral with congruent diagonals but no right angles is not necessarily a parallelogram. In order for a quadrilateral to be classified as a parallelogram, it must have both pairs of opposite sides parallel. The property of having congruent diagonals does not guarantee that the sides are parallel, so the quadrilateral may not be a parallelogram.
yes because a square is, by definition, a shape having 4 ninety degree angles, and four congruent sides
A rectangle and a square are two types of quadrilaterals having four equal angles, where each of them equals a right angle.
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.
A square has 4 congruent sides and 4 right angles, in addition to having all of the properties of a parallelogram. A kite is not a parallelogram. It has two pairs of consecutive congruent sides, and a pair of congruent opposite angles.
A quadrilateral having four right angles is called a rectangle.
No, definition of rhombus is having four congruent sides, but that means its angles don't have to be all congruent. A square is having four congruent sides and angles.
