What is the difference of a trapezoid and an isosceles trapezoid

The video tutorial covers the basic properties of trapezoids, focusing on the distinction between regular and isosceles trapezoids. It explains that trapezoids have one pair of parallel sides, called bases, and the other sides are called legs. The tutorial emphasizes the characteristics of isosceles trapezoids, which have congruent opposite sides and angles, and equal diagonals. It also highlights that unlike parallelograms, the diagonals of trapezoids do not bisect each other. The session concludes with a brief mention of the mid-segment theorem.

What is a key difference between a trapezoid and a parallelogram?

• A trapezoid has no parallel sides.

• A trapezoid has two pairs of parallel sides.

• A trapezoid has only one pair of parallel sides.

• A trapezoid has three pairs of parallel sides.

In a trapezoid, what are the parallel sides called?

• Bases

• Diagonals

• Vertices

• Legs

Which of the following is true for an isosceles trapezoid?

• Opposite sides are not congruent.

• Opposite angles are not congruent.

• Opposite sides are congruent.

• Diagonals are not equal.

If one side of an isosceles trapezoid is 5 units, what is the length of the opposite side?

• 10 units

• 5 units

• 3 units

• 7 units

What is a characteristic of the diagonals in an isosceles trapezoid?

• They are equal in length.

• They are perpendicular.

• They are parallel.

• They bisect each other.
