Answer 1

Answer:

tapezoid - a quadrilateral with 1 pair of parallel opposite sides and 1 pair of non-parallel opposite sides

isosceles trapezoid - a quadrilateral with 1 pair of parallel opposite sides and one pair of non-parallel congruent sides

Answer 2

Answer:

Step-by-step explanation:

The typical isosceles trapezoid will have a uniform width, measured vertically, but two ends that are not square (not perpendicular to the x-axis.  The two sloping ends are congruent (their slopes have exactly the same slope.

The same could be said of an isosceles trapezoid that is vertical; the sloping ends have the same slope.
