Question

which statements are correct regarding the properties of trapezoids? check all that apply. the diagonals of an isosceles trapezoid are congruent. the bases of a trapezoid are parallel. the adjacent sides of a trapezoid are congruent. base angles of a trapezoid are congruent. the diagonals of a trapezoid are perpendicular.

Explanation:

1. By definition, an isosceles trapezoid has congruent diagonals.
2. A trapezoid is defined as a quadrilateral with one - pair of parallel sides (the bases).
3. Adjacent sides of a trapezoid are not necessarily congruent.
4. Only in an isosceles trapezoid are the base - angles congruent, not in all trapezoids.
5. The diagonals of a trapezoid are not necessarily perpendicular.

Answer:

The diagonals of an isosceles trapezoid are congruent.
The bases of a trapezoid are parallel.
