What are some characteristics of an isosceles trapezoid

The video tutorial explains the properties of quadrilaterals, focusing on the equality of opposite sides and angles. It highlights the unique properties of diagonals in different quadrilaterals, such as parallelograms and trapezoids. Specifically, it discusses how diagonals in isosceles trapezoids are congruent but do not bisect each other, unlike in parallelograms. The tutorial concludes by stating that proving congruent diagonals can confirm a trapezoid is isosceles.

Which of the following is true about the opposite sides and angles of a trapezoid?

• Opposite sides and angles are never equal.

• Opposite sides are always unequal.

• Opposite angles are always unequal.

• Opposite sides and angles can be equal.

How do the diagonals of trapezoids differ from those of parallelograms?

• Trapezoid diagonals do not bisect each other.

• Trapezoid diagonals are always longer.

• Trapezoid diagonals bisect each other.

• Parallelogram diagonals do not bisect each other.

What is a unique property of the diagonals in isosceles trapezoids?

• They are unequal.

• They are parallel.

• They are congruent.

• They are perpendicular.

What can be concluded if the diagonals of a trapezoid are congruent?

• The trapezoid is equilateral.

• The trapezoid is isosceles.

• The trapezoid is scalene.

• The trapezoid is right-angled.

Which statement is true about the diagonals of an isosceles trapezoid?

• They bisect each other.

• They are always unequal.

• They form right angles.

• They are congruent.
