Only if it is an isosceles trapezoid which has one line of symmetry.
median = 29
in an isosceles triangle
FALSE
An isosceles trapezoid, or any trapezoid, does not have diagonals that bisect each other.
No, the diagonals of a trapezoid do not necessarily bisect each other. Only in an isosceles trapezoid, where the two non-parallel sides are congruent, will the diagonals bisect each other. In a general trapezoid, the diagonals do not bisect each other.
No.
Usually they do not, but in an isosceles trapezoid they do.
Since EF is a median, it will bisect side AD. Therefore, x = DC. In trapezoid ABCD, the bases are side AD and side BC. However, from the information given, we cannot determine the value of x without additional details.
