Question

Trapezoid A B C D is shown. Diagonals are drawn from point B to point D and from point A to point C and intersect at point E.
If quadrilateral ABCD is an isosceles trapezoid, which statements must be true? Select three options

BC ∥ AD
BD ⊥ AC
BA ≅ CD
BE ≅ ED
∠CBA ≅ ∠BCD

Answer 1

BC is parallel to AD, AB is equal to CD and ∠CBA ≅ ∠BCD

Isosceles trapezoid

An isosceles trapezoid is a quadrilateral (has four sides and four angles) in which the bases are parallel, base angles are equal, legs are equal and the diagonals are equal.

In trapezoid ABCD, BD and AC are the diagonals. Hence:

BC is parallel to AD, AB is equal to CD and ∠CBA ≅ ∠BCD
