A parallelogram has both pairs of opposite sides parallel. A trapezoid has only one pair of sides parallel.
The information given would suggest that the polygon in question is an isosceles trapezoid and not a parallelogram
I have never come across the phrase "parallel angles". Please elaborate.
One pair? If it is one pair of parallel sides, then it is a trapezoid. If it has 2 pairs of parallel sides, then it is a parallelogram.
A trapezium.
