No, a trapezoid cannot have 3 bases. A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases of the trapezoid. Therefore, there can only be 2 bases.
Work out each figure separately then add them together: Area of a trapezoid = 0.5*(sum of parallel bases)*height Area of a rectangle = length*height
The area of a trapezoid is equal to the height, multiplied by the average of the two widths.
Area of a trapezoid = 0.5*(sum of parallel sides)*height
If you take a regular four sided pyramid and chop off the top, parallel with the base, the left over piece would be a solid with four identical trapezoidal faces and a square top and bottom. The only name I know is 3-D trapezoid.
Never. It's impossible. If there are two acute angles, it means there have to be two obtuse angles, so three acute angles is impossible.
The altitude of a trapezoid bisects the bases of the trapezoid.
The average of the bases of a trapezoid is the median.
The bases on a trapezoid are the two lines that are parallel to each other. .............................. ....____base____...... .../ ...................\..... ../ .....................\.... ./_____base_____\... .............................
A trapezoid does not have three bases!
False.
The area of a trapezoid is 1/2 * (base 1 + base 2) * height, so the area of this trapezoid = 0.5*(3+7)*3 = 15 square yards
It is 5 inches.
If a segment is parallel to the bases of a trapezoid, it is indeed the median of the trapezoid. The median connects the midpoints of the non-parallel sides and is equidistant from both bases. Additionally, the length of the median is the average of the lengths of the two bases. Thus, it effectively bisects the trapezoid into two smaller trapezoids.
The formula for area a is height X average of the two parallel bases of the trapezoid. In this instance, a = 3[(7 + 5)/2] = 18 square centimeters.
They are parallel
sometimes
The bases of a trapezoid are either of its parallel sides.
