What shape has four congruent sides an 4 right angles?
A square always has, and any polygon with more than four sides can have.
What does proportional mean in math terms?
In math, proportional means that two quantities always have the same relative size. For example, the lengths of these two shapes are proportional (one shape's length is always twice as large as the other.)
Why is the sum of the exterior angle measures of a convex polygon is always 360 degrees?
It is because if you shorten the sides yet keep the angles the same size, the shape will eventually become a pinwheel and thus, because a circle is always 360 degrees, the outer angles will always be 360 degrees.
Is it true that a four sided shape is always a square why?
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.
What does N0 always equal?
It does not always equal anything because it depends on the context. In chemistry, for example, it means nitric oxide or nitrogen monoxide. In conversation it is a negative. If written in block capitals, it would indicate an emphatic negative. There are other possibilities such as a side of the shape: NOPQ
