square
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.
The purpose for this question determines the which of the three answers is most accurate.1. A rhombus is defined as "four-sided shape [quadrilateral] where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. ... " As such, a "traditional" rhombus would look like a square that is "leaning" to one side or another. This particular rhombus would have NO right angles.2. A third portion of the definition above is " the diagonals [lines that connect two opposite angles] of a rhombus bisect each other at right angles." So, the point of intersection of the diagonals produces four right angles for purposes that are beyond the scope of this question and answer.3. Based on the definitions of a quadrilateral and rhombus, a square is, therefore, a rhombus. As a result, a rhombus that is a square has FOUR right angles in its shape and four right angles at the point of intersection of its diagonals.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Three rhombi. Alternatively, a rhombus, and two irregular polygons with 5 or more sides, forur of which are equal. Apart from a rhombus there is no 4-sided shape that has equal sides but no right angles.
a Pentagon is five sided and CAN have 3 right angles.
a decagon
Regular square: A square with all equal sides and right angles. Rectangle: A square with all right angles but unequal sides. Rhombus: A square with all sides equal in length but angles are not necessarily 90 degrees.
A square, a rhombus and a kite are three examples of quadrilaterals that have perpendicular diagonals that intersect each other at right angles.
A triangle can never have three right angles
An irregular hexagon.
No REGULAR polygon can have three right angles in it. Any polygon with five or more sides CAN have three right angles, as long as it's not regular.
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
