### Right-angled trapezoid

Right-angled trapezoid is a plane figure composed of four straight line segments and four interior angles, totaling, 360 degrees, two of them necessarily of 90 degrees.
The straight lines segment, not parallel, are called sides or legs, while the two parallel segments are called bases, one short and the other long.
Like, any trapezium, the right-angled trapezoid has as follow:
a) Area;
b) Perimeter: sum of the lengths of the bases and sides;
c) Altitude: perpendicular distance from the base to the other;
d) Median: line joining the midpoints of two sides;
e) Diagonal: straight line segment that connect the vertices of the opposite angles.
To calculate the elements of the right-angled trapezoid, enter the two bases, and one of the two sides. Use the point as decimal separator. Ex 1,300.34 enter: 1300.34; The results will be shown after a click on Calculate.
