question 5 1 pts isosceles trapezoids are trapezoids true false question 6 1 pts in a square all sides are congruent true false question 7 1 pts parallel sides of an isosceles trapezoid are congruent true false question 8 1 pts all quadrilaterals have 4 congruent sides true false

Explanation:

Question 5

An isosceles trapezoid is a type of trapezoid. By definition, a trapezoid has at least one pair of parallel sides, and an isosceles trapezoid has the additional property of non - parallel sides being congruent and base angles being equal. So isosceles trapezoids are trapezoids.

A square is a quadrilateral with four equal - length sides (congruent sides) and four right angles. By the definition of a square, all its sides are congruent.

In an isosceles trapezoid, the non - parallel sides (legs) are congruent, and the parallel sides are called bases. The bases of an isosceles trapezoid are not congruent. The legs are congruent, but the parallel sides have different lengths (except in the special case when it is a rectangle, but a rectangle is a different type of quadrilateral). So the parallel sides of an isosceles trapezoid are not congruent.

Answer:

True
