No. The other two sides are congruent.
False.
They are congruent angles.
No, an isosceles trapezoid does not have four congruent sides. An isosceles trapezoid has a pair of parallel sides (the bases) and the non-parallel sides (the legs) are of equal length, but the lengths of the bases are generally different. Thus, it has only two pairs of congruent sides, not four.
C. Congruent Bases
The base angles are congruent in an isosceles trapezoid
In an isosceles trapezoid, the non-parallel sides (the legs) are congruent, but the consecutive sides (one leg and one base) are not necessarily congruent. The two bases (the parallel sides) are also not equal unless the trapezoid is a rectangle. Thus, while the legs of an isosceles trapezoid are congruent, the consecutive sides are not.
Opposites sides of an isosceles trapezoid are congruent
A trapezoid with congruent diagonals is an isosceles trapezoid.
