A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. Right trapezoids are used in the trapezoidal rule for estimating areas under a curve. An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base. An isosceles trapezoidis a trapezoid where the base angles have the same measure. As a consequenc

The Acme thread form has a 29° thread angle with a thread height half of the pitch; the apex (or crest) and valley (or root) are flat.This shape is easier to machine (faster cutting, longer tool life) than a square thread. The tooth shape also has a wider base which means it is stronger (thus, the screw can carry a greater load) than a similarly sized square thread.

The next proof of the Pythagorean Theorem that will be presented is one in which a trapezoid will be used. Figure 15. By the construction that was used to form this trapezoid, all 6 of the triangles contained in this trapezoid are right triangles. Thus, Area of Trapezoid = The Sum of the areas of the 6 Triangles

Since the skirt is made of a series of stitched sectional panels, these measurements are divided according to the amount of panels in your skirt design. Once complete, the gored pattern generally resembles an elongated triangle shape with the top point horizontally snipped away, producing a trapezoid-like pattern.
