A trapezoid has 1 set of parallel lines
Not sure how you can have only one parallel side. What is it parallel to?
well... i hav no idea!
line
a 2 sided shape is real but a 1 sided shape is not
A 1 dimensional shape is a line.
a heart
Trapezium
1
the shape is a heart.
in order to draw a potier triangle u need to obtain 2 curves namely O.C.C(open circuit curve) and full load zero power factor curve. 1.Draw a tangent to the o.c.c thro origin call it OB (air line) 2.Draw a line PQ parllel and equal to OA where OA is the distance between the 2 curves and it lies on the x axis. 3.from pt Q draw a line parllel to OB such that it intersects the O.C.C at R. and there you are, PQR is the required potier triangle....
it behaves like a line
A vertical line
