Rectangles - and squares, as a special case.
They are a square and a rhombus
A rhombus is a type of parallelogram. Parallelograms are types of quadrilaterals. Everything that applies to quadrilaterals and parallelograms apply to rhombuses.Quadrilaterals have four sides and four angles.Parallelograms have at two pairs of opposite sides and opposite angles congruent. (Note: congruent is pretty much "equal", except for geometric figures). Both pairs of opposite sides are also parallel, hence the name "parallelogram".Rhombuses have all sides congruent.
Equal angles.
RectangleA rectangle has 4 congruent angles, but two pairs of congruent sides instead of all sides being congruent.
Quadrilaterals.
They are a square and a rhombus
A square and a rhombus are 4 sided quadrilaterals that have congruent sides
A square, but not a rhombus because a rhombus does not have four congruent angles
All rhombuses have two pairs of congruent angles (opposite angles are congruent to one another - a square is a special case type of rhombus in which all four angles are congruent).
A rhombus is a type of parallelogram. Parallelograms are types of quadrilaterals. Everything that applies to quadrilaterals and parallelograms apply to rhombuses.Quadrilaterals have four sides and four angles.Parallelograms have at two pairs of opposite sides and opposite angles congruent. (Note: congruent is pretty much "equal", except for geometric figures). Both pairs of opposite sides are also parallel, hence the name "parallelogram".Rhombuses have all sides congruent.
A rhombus is a quadrilateral whose four sides are congruent. Squares are a type of rhombus with congruent angles. Since there are 4 contruent angles, they must all be right angles.So any quadrilateral that is equilateral is a rhombus and any rhombus with 4 right angles is a square. Every rhombus is a parallelogram because the opposite angles of a rhombus are congruent. Also, the diagonals of a rhombus are perpendicular.
A rhombus is a parallelogram with four equal sides. A square is a type of rhombus.
Equal angles.
:D I think that it is a rhombus cause a rhombus has four congruent sides but may not be a square or a rectangle.
RectangleA rectangle has 4 congruent angles, but two pairs of congruent sides instead of all sides being congruent.
Adjacent angles
An equilateral triangle.
