It is impossible to have a six sided shape with right angles since the lines would never meet, therefore it would not create a shape. The most right angles you can have in a shape is four. A six sided shape is called a hexagon. There are Regular Hexagons, meaning all the sides and all the angles are equal. Any other Hexagon with unequal sides and angles and called Irregular Hexagons. Each side must be straight, and the sum of the angles equaling 720°.
Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
A rhombus is a four sided polygon which like all other four sided shapes are known as quadrilaterals. What they all have in common is that the total sum of their interior angles add up to 360 degrees.
No, a four sided shape is not always a square. The mathematical name for a four sided shape is a QUADRILATERAL. The definition of a square is a four sided shape with four equal sides and angles, internal angles totalling 360 degrees and four lines of symmetry. If a shape has all of these properties, it is a square.Possibilities for a four sided shape areAs said above, all are called quadrilaterals, but some have special propertiesA Parallelogram, which has opposite sides parallel to each othera Rhombus, which has all sides equal and parallel, but not necessarily with right anglesA Rectangle, which is a parallelogram with right angles.A Square, which is a rhombus rectangle. All four sides equal, all angles equal and right, all diagonals bisecting each other. It really is hip to be square.
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
