Trapezoid Shape

Properties of a Trapezoid shape. Learn all about this quadrilateral and the properties that are unique to a trapezoid. Welcome to MooMooMath and Science In this video I would like to talk about the properties of a trapezoid A trapezoid is a quadrilateral with one pair of parallel sides and one pair of non parallel sides Because a trapezoid is a quadrilateral it has 4 sides Because a trapezoid only has one pair of parallel sides it is not considered a parallelogram Take a look at this house Do you see any trapezoids? Is this geometric shape a trapezoid No because it does not have one pair of parallel sides The roof is a trapezoid The base of a trapezoid is created by the two parallel sides Notice that the two bases are parallel The non parallel sides are called legs When you add all of the interior angles it equals 360 degrees. The angles on each side are supplementary which means they add to 180 degrees Because a trapezoid is a closed figure it has four corners which are called vertices The median is a segment that connects the midpoint of the two legs The median is parallel to bases and equals half the length of the two bases Therefore, you can find the length of the median by adding the length of the two bases and divide by two Two types of trapezoid A right trapezoid has two right angles that are next to each other. This is called consecutive An isosceles trapezoid has two equal legs Which results in the diagonals are equal length And the base angles are congruent You can find the area of a trapezoid by taking ½ base 1 + base 2 times the height The height is not the side length but a line that is perpendicular to the base In order to find the perimeter just add the length of the four sides A + B +C + D There you go the properties of a trapezoid
