Trapezoids actually have 5 angles (Including the straight angle).
noIt has 2 obtuse angles and 2 acute angles though.
Yes.
Isosceles trapezoids have 2 (occasionally 3) equal sides and have 2 pairs of equal angles, but that's not case if they're not isosceles.
If you mean on opposite sides yes. There are 2 pairs of congruent angles.
Yes but not more than 2
The trapezoids have 4 angles
Yes a trapezoid can have 2 obtuse angles and 2 acute angles whereas its 4 interior angles add up to 360 degrees.
Yes. Those trapezoids with four right angles are called squares. Since in order to be a trapezoids, a shape must be a quadrilateral with with one set of parallel lines, and a square fits those requirements. In conclusion, the trapezoids that have four right angles are squares.
No
no because then it is not a trapezoid.
An isosceles trapezoid has 2 pairs of equal angles of different sizes and they add up to 360 degrees
They all have 4 interior angles.
