They are all 60 degrees.
A rectangle (or square).
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.

They are all 60 degrees.
A rectangle (or square).
All right angles are congruent, and all straight angles are congruent.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
Rectangles have all angles congruent,
Two angles that are congruent to each other and are on opposite sides of the parellel lines
Only if the lines cut by the transversal are parallel.
a polygon that has all angles congruent is an equiangular .....
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
