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.
What does a trapezoid equal?
Explanation: All quadrilaterals’ interior angles sum to 360°. In isosceles trapezoids, the two top angles are equal to each other. Similarly, the two bottom angles are equal to each other as well.
What is 2 pairs of parallel sides?
Parallelogram: A quadrilateral with 2 pairs of parallel sides. Rectangle: A parallelogram with 4 right angles.
What does trapezium mean?
Trapezium, describing a geometric shape, has two contradictory meanings: Outside the US and Canada: a quadrilateral with at least one pair of parallel sides (known in the US as a trapezoid) In the US and Canada: a quadrilateral with no parallel sides (known elsewhere as a general irregular quadrilateral)
