a square. all of the angles are 90 degrees or pi/2 radians.
quadrilateral
triangle isosceles triangle
A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
A pentagon. If the sides and angles are equal it is a REGULAR pentagon.
A 1000-sided shape is called a chiliagon. It is a polygon with 1000 sides and 1000 angles. The sum of the interior angles of a chiliagon is 179,640 degrees. It is a regular polygon, meaning all its sides are of equal length and all its angles are equal.
A parallelogram is defined as a four-sided shape, with opposite sides of equal length and opposite angles equal.
A parallelogram is a four sided shape where each of the two opposite sides are parallel. A consequence of this is that opposite sides are equal in length, and opposite angles are also equal.
A square is a four-sided shape with all sides equal and all angles equal.
A rhombus is a 4 sided shape, all sides of equal length, opposite sides parallel and opposite angles are equal, also the diagonals bisect each other at right angles.
Square because all lines are opposite and all angles are 90 degrees.
A rhombus is a 4 equal sided quadrilateral with equal opposite acute angles and equal opposite obtuse angles with diagonals that bisect each other at right angles.
They are alternate angles which are equal in size
It is no different from a quadrilateral.A quadrilateral is any shape with four sides and a rhombus has four sides, therefore it is a quadrilateral.
A 7-sided shape is a heptagon.If all the sides are of equal length and the angles are all equal then it is known as a regular heptagon.
If you mean a rhombus then some of its properties are:- It's a 4 equal sided quadrilateral shape It has 2 opposite equal acute angles and 2 opposite equal obtuse angles Its 4 interior angles add up to 360 degrees Its 2 diagonals intersect each other at right angles It will tessellate
A rhombus is a 4 equal sided quadrilateral with opposite parallel sides and equal opposite acute angles and equal opposite obtuse angles that all add up to 360 degrees.
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
