What are trapezoid angles?

The sides and angles of a trapezoid: trapezoid. The bases (top and bottom) of a trapezoid are parallel. That's it. No sides need to be congruent and no angles need to be congruent. Nothing special happens with the diagonals. read more

Adjacent Angles of Trapezoid. The angles on the same side of a leg are called adjacent angles such as $$\angle A $$ and $$ \angle D $$ are supplementary. For the same reason, $$ \angle B $$ and $$ \angle C $$ are supplementary. read more

A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. Right trapezoids are used in the trapezoidal rule for estimating areas under a curve. An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base. read more

Since a trapezoid has four sides, it has four angles. Trapezoids are named by their four angles, or vertices, such as "ABCD." Determine if the trapezoid is an isosceles trapezoid. read more
