Question

Four properties of a trapezoid

Answer 1

The bases are parallel to each other.

Angles next to each other sum up to 180°

The lower base angles are congruent.

The upper base angles are congruent.

Explanation:

Answer 2

The bases (the top and bottom) are parallel to each other.
Opposite sides of a trapezoid (isosceles) are of the same length.
Angles next to each other sum up to 180°
The median is parallel to both the bases.
Median's length is the average of both the bases i.e. (a +b)/2. You’re welcome!
