Isosceles trapezium(trapezoid)
When a transversal line cuts through parallel lines various angles are created such as equal corresponding angles and equal alternate angles as well as other types of angles.
There are 56 pairs of congruent angles.
The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
A square or rectangle are the only regular polygons, but many other shapes have two right angles and two parallel lines.
No, a trapezoid does not have four obtuse angles. A trapezoid has one pair of parallel sides and the other pair of non-parallel sides. The angles of a trapezoid can be a combination of acute, obtuse, and right angles, but it cannot have four obtuse angles.
That's a rectangle (possibly a square). If two sides are parallel, and all angles are right angles, then the other two sides must be parallel also.
Parallel refers to lines and not angles A right angle is formed by 2 lines that are perpendicular to each other and not parallel If you already have a line and you draw two lines which are at right angles to it, those two lines are parallel.

When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.

Either they are parallel to or they intersect each other.
Because they are angles that are subtended by pairs of sides that are parallel to each other. There are several ways of proving the angles are equal.
they are angles that are usually parallel and that crossed the line that are oppsite from each other
No parallel lines do not form angles because they remain the same distance apart from each other. But angles are formed when a transversal line cuts through them
