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....
Lines of Latitude, as in "changes in latitude, changes in attitude."
A trapezoid has 1 set of parallel lines
It's hard to tell, since there really is no such thing as "parallel angles". One thing we do know for sure . . . a triangle can't have two parallel sides.
if the triangle is a right angle it has 2 perpendicular line segments.
Capital letters of: E F H Z N and M all have parallel lines
2 pairs of parllel sides
Line segments are lines so the answer is 3.
Three pairs. The line joining the midpoints of any two sides of a triangle is always parallel to the third side of the triangle (and half its length).

There is only one line of symmetry in an isosceles triangle. If you draw this triangle with the "odd" side as the base and then bisect it with a vertical line, you will have that one line of symmetry. The triangle can be folded in half along this line because each side is a mirror of the other.
