a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Four equal sides and no right angles
Yes it is a polygon with 4 equal sides but has no interior right angles
A square is a plane rectangle with four equal sides and four right angles, a four-sided regular polygon, and a rhombus having four right angles.
An equalateral triangle
No, but an equilateral triangle is a regular polygon with 3 equal sides and 3 equal angles.
No. Not all angles are equal, and not all sides are equal - and both conditions must be fulfilled for a "regular polygon".
A square has 4 right angles and 4 equal sides.
A rhombus would fit the given description.
A parallelogram is a four sided polygon with opposing parallel sides of equal length. Then if it has four right angles, the polygon becomes a rectangle.
Sum of interior angles of a polygon = (2n - 4)right angles 1260 = (2n - 4) x 90 1260 = 180n - 360 900 = 180n n = 5, it is a pentagon
a regular polygon with 4 equal sides and 4 right angles.
It's called a rhombus.
A rhombus or a parallelogram
That would be a square.
