Question

problem 9:
(first taught in
lesson 51)
complete this sentence by selecting always,
sometimes, or never.
a trapezoid is ______ isosceles.
after you pick your answer press go.
a. always b. sometimes c. never

Explanation:

A trapezoid is a quadrilateral with at least one pair of parallel sides. An isosceles trapezoid is a specific type of trapezoid where the non - parallel sides (legs) are congruent. Since there are trapezoids that are not isosceles (with non - congruent legs) and there are trapezoids that are isosceles, the statement "A trapezoid is isosceles" is not always true (because of non - isosceles trapezoids) and not never true (because isosceles trapezoids exist).

Answer:

B. sometimes
