# What is the formula for the median of a trapezoid?

## What is the formula for the median of a trapezoid?

The length of the median is the average of the two bases, so you can find it with the formula: ((length of one base) + (length of the other base)) / 2.

## What is the Midsegment theorem of a trapezoid?

Theorem 1: If a line through the midpoint of a leg of a trapezoid is parallel to its bases, then the line passes through the midpoint of the other leg. Theorem 2: The midsegment of a trapezoid is half the lengths of the two parallel sides.

## What are the theorems of trapezoid?

THEOREM: If a quadrilateral (with one set of parallel sides) is an isosceles trapezoid, its legs are congruent. THEOREM: (converse) If a trapezoid has congruent legs, it is an isosceles trapezoid. THEOREM: If a quadrilateral is an isosceles trapezoid, the diagonals are congruent.

## How many medians does a trapezoid have?

Recall that the median of a trapezoid is a segment that joins the midpoints of the nonparallel sides. Theorem 55: The median of any trapezoid has two properties: (1) It is parallel to both bases. (2) Its length equals half the sum of the base lengths.

## What is half of a trapezoid called?

Median of a Trapezoid The median (also called a midline or midsegment) is a line segment half-way between the two bases.

## Can a rectangle be a trapezoid?

Properties of a trapezoid A trapezoid can be a rectangle if both pairs of its opposite sides are parallel; its opposite sides are of equal length and are at right angles to each other.

## Is Square a trapezium?

A trapezium is a trapezoid, therefore it cannot be a square. A square has four congruent sides and angles. The most congruent sides a trapezium can have is three. The most congruent angles it can have is two.

## How do you know if its a trapezoid?

The definition of a trapezoid is: a quadrilateral with only two parallel sides. If the shape you’re looking at doesn’t have at least one set of parallel sides, it’s not a trapezoid; it’s something called a trapezium instead. Similarly, if the shape has two sets of parallel sides, it’s not a trapezoid.
