Question

Which statement is true?

A.
An isosceles trapezoid is a rectangle because its opposite sides are parallel.
B.
An isosceles trapezoid has perpendicular diagonals.
C.
An isosceles trapezoid has opposite angles that are congruent.
D.
An isosceles trapezoid has congruent base angles.

Answer 1

The correct answer is D) An isosceles trapezoid has congruent base angles.

Explanation:

It is not A because it only has one set of parallel sides.

It is not B because it has congruent bisecting diagonals.

It is not C because if its opposite angles were congruent it would be a rhombus.

Answer 2

I believe the correct answer from the choices listed above is option D. It is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. It is a special type of trapezoid.

Hope this answers the question. Have a nice day.
