In the case of a quadrilateral, a kite or arrowhead. But it could be an irregular version of a polygon with 5 or more sides.
A parralelogram
Yes, it is true that a kite has one pair of opposite congruent angles. In a kite, the angles between the distinct pairs of adjacent sides are equal, leading to one pair of opposite angles being congruent. The other pair of opposite angles in a kite is generally not congruent.
parallelogram
It has one pair.
Yes, in a parallelogram, opposite angles are congruent. This means that each pair of opposite angles has the same measure. Additionally, the consecutive angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
Yes, an isosceles trapezoid has one pair of congruent opposite sides and congruent base angles
No. A square has two pairs of congruent angles!
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
Vertically opposite.
Yes, it is.
A parallelogram has the 2 pair of opposite congruent sides, but a rectangle (special case of parallelogram) also has the four congruent angles.
parallelogram
It has one pair.
If this concerns quadrilaterals and the fact that the specified quadrilateral must ALWAYS have exactly one pair of opposite angles, then the shape is classified as a kite.* * *I'm in grade nine geometry classes. It's great fun. *slight sarcasm*
