what do you mean by points? do you mean angles or sides?
Case No. 1 :-General geometrical closed figureAns. :- PERIMETERCase No. 2 :-Circular geometrical closed figureAns. :- CIRCUMFERENCE
the perimeter is the sum of the length of every side of the geometrical figure. In your case, since you have 4 sides two of which are equal, the perimeter would be 2*(a+b) where a and b are the length of two sides
The best way to find out if 2 points have equal elevation is to measure them. You must measure each of these points.

i have no clue you try to figure it out
a parallelogram
The 'classic' arrow-head shape has 7 angles.
That would either be a quadrilateral (2-Dimensional) or a tetrahedron (3-Dimensional) Note that the meaning of "side" is a bit different depending on whether you are talking 2-D or 3-D.
a pentagon
They are all points on the [Real] number line.However, different irrational numbers: pi, sqrt(2), e, phi etc have different geometric applications.
