question 14
select the properties of an isosceles trapezoid
all 4 angles are congruent(right)
both pairs of opposite sides are congruent
2 pairs of consecutive congruent sides
diagonals bisect each other
one pair (legs) of opposite sides congruent
all 4 sides are congruent
exactly one pair of opposite angles congruent
diagonals are congruent
both pairs of opposite angles are congruent
both pairs of opposite sides are parallel
diagonals bisect both pairs of opposite angles
has 4 sides
all pairs of consecutive angles are supplementary
diagonals are perpendicular
both pairs of base angles are congruent
exactly one pair of parallel sides

Explanation:

An isosceles trapezoid is a quadrilateral (so it has 4 sides). It has exactly one pair of parallel sides (the bases). The non - parallel sides (legs) are congruent. The base angles (the angles adjacent to each base) are congruent. The diagonals of an isosceles trapezoid are congruent. Also, because it has one pair of parallel sides, by the property of parallel lines and transversals, all pairs of consecutive angles are supplementary.

Answer:

• one pair (legs) of opposite sides congruent
• Diagonals are congruent
• Has 4 sides
• All pairs of consecutive angles are supplementary
• Both pairs of base angles are congruent
• Exactly one pair of parallel sides
