No. A trapezoid is not a triangle at all
a parallelogram,a right triangle and a triangle
Depending how you halve it can be a right angle triangle or an isosceles trapezoid
The trapezoid contains 180 more degrees.
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
Triangle: Half the product of the longest side and the perpendicular distance from it to the apex. Trapezoid: Half the product of the sum of its bases and the height.
right triangle
A trapezoid and a triangle make a paralellogram.
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.
No because a trapezoid has 4 sides and a triangle has three if a trapezoid had three then it would be a triangle. If you had 3 trapezoids you could make a triangle!
It is a square with a right angle triangle attached to it having the same height as the square.
An isosceles triangle and a isosceles trapezoid.
