A trapezoid has four angles.
No, for two reasons. First of all, a trapezoid has only 4 angles, so you can't have 5 angles, or it would be a pentagon. Second of all, the maximum number of obtuse angles someone can have in a trapezoid is two.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
The base angels of a trapezoid are the angles that attach to the legs of the trapezoid. There are four base angles in a trapezoid.
There must be exactly one.
The base angles are congruent in an isosceles trapezoid
The base angles of an isosceles trapezoid are congruent
A trapezoid has two sets of equal angles
Every Trapezoid has 4 angles.An isosceles trapezoid has 2 acute angles.?
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
