Why is the formula for area of a triangle and area of a trapezoid are what they are?
area triangle = 1/2 base times height area trapezoid = 1/2 (sum of bases) times height
How is the formula for the area of a trapezoid related to the formula for the area for a triangle?
The formula for the area of a trapezoid is A = 1/2 (b1 + b2)/h where b1 is the upper base of the trapezoid , b2 is the lower base of the trapezoid and h is the height of the trapezoid. Since a triangle has only one base , replace either b1 or b2 with zero. Thus the area of a triangle is A = 1/2bh
what 3 shapes can be assembled to make a trapezoid?
a parallelogram,a right triangle and a triangle
What is half of an isosceles triangle?
Depending how you halve it can be a right angle triangle or an isosceles trapezoid
Which is not a quadrilateral a rhobus a rectangle a right triangle or a trapezoid?
It is the right angle triangle which has 3 sides whereas all quadrilaterals have 4 sides.
Is a right triangle a trapezoid?
No. A trapezoid is not a triangle at all
Is a trapezoid an equilateral right triangle?
No. A trapezoid is not a triangle at all

How can you find the area of a composite figures trapezoid with a triangle?
To find the area of a composite figure consisting of a trapezoid and a triangle, you would first calculate the area of the trapezoid using the formula A = (1/2)h(b1 + b2), where h is the height of the trapezoid and b1 and b2 are the lengths of the two parallel bases. Then, you would calculate the area of the triangle using the formula A = (1/2)bh, where b is the base of the triangle and h is the height. Finally, you would add the areas of the trapezoid and the triangle together to find the total area of the composite figure.

What is the difference in the amount of degrees that a right angled trapezoid contains and a right isosceles triangle?
The trapezoid contains 180 more degrees.
What shape can make a trapezoid and triangle?
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
What is a trapezoid with one side perpendicular to the parallel sides?
right triangle
What does a triangle and a trapezoid makes?
A trapezoid and a triangle make a paralellogram.
How many trapezoid in a triangle?
A triangle cannot be formed by any number of trapezoids. Every time a trapezoid is stretched across one side of a triangle, a smaller triangle similar to the first is formed by the part not covered by the trapezoid. Unless... the triangle was equilateral and the trapezoids were isoceles. You could fill the triangle with 3 trapezoids as follows: Use the longer 'bottom' edge of each trapezoid and the 'left' edge of the next trapezoid to make up the edge of the triangle. The shorter 'top' edge of the trapezoids touch the 'right' edge of the next trapezoid in the center of the triangle.
