A square has 4 equal sides with 4 right angles.
It is a square that has 4 equal sides and 4 right angles.
A seven sided shape (with seven angles) is called a heptagon.
That shape is a square. A square is a special kind of rhombus, and a rhombus is aspecial kind of parallelogram. So the shape described in the question is a square,a rhombus, and a parallelogram.ALSO . . . any polygon with more than four sides can have four equal sidesand four right angles.
Rhombus
A square has 4 equal sides with 4 right angles.
A parallelogram has both pairs of opposite sides parallel but no right angles. A special kind of parallelogram is a rhombus which has all its sides of equal length
There cannot be a triangle which has 2 equal sides and 3 equal angles. The number of sides and angles which are equal must be the same: 0, 2 or 3.
It is a square that has 4 equal sides and 4 right angles.
A seven sided shape (with seven angles) is called a heptagon.
A triangle that has three equal sides, and therefore three equal angles, is called an equilateral triangle.
Isosceles
That shape is a square. A square is a special kind of rhombus, and a rhombus is aspecial kind of parallelogram. So the shape described in the question is a square,a rhombus, and a parallelogram.ALSO . . . any polygon with more than four sides can have four equal sidesand four right angles.
Square.
Rhombus
A parallelogram has two sets of parallel sides. It can have four sides that are equal in length. That is why a square is also a parallelogram. You can have a parallelogram with two sets of parallel sides, all of which are equal in length, but they do not meet in right angles. It looks kind of like a lopsided or squished square, and it is called a rhombus.
