They are alternate angles which are equal in size
An interior angle is an angle defined by two sides of a polygon and that is inside the polygon. Opposite interior angles are specific pairs of interior angles, those that are opposite each other in the polygon. Alternate or opposite interior angles are also angles that lie on opposte sides of the tranversal line that cuts through parallel lines.
The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.
When two parallel lines are both intersected by a tranversal which is a nonvertical line, otherwise all angles formed by that intersection are right angles.
Angles on opposite sides of the transversal and between the parallel lines
Yes
Not too sure about the given description but they could be equal alternate angles.
square
Those are "alternate interior" angles. They're always equal.
The opposite sides in a parallelogram are parallel and the same length. However, they are not angles at 90 degrees (right angles).
2 opposite acute angles and 2 opposite obtuse angles with opposite parallel sides
trapezoid is the answer!
rhombus
