Right Trapezoid Calculator

Calculations in a right trapezoid (or right trapezium). This is a trapezoid with two adjacent right angles. Enter the lengths of the two parallel sides a and c and either base b or slant side d. Choose the number of decimal places and click Calculate. Angles are calculated and displayed in degrees, here you can convert angle units.


Euclid Long side (a): Right Trapezoid
Base (b):
Short side (c):
Slant side (d):
Diagonal e:
Diagonal f:
Central median (m):
Perimeter (p):
Area (A):
Acute angle (α):
Obtuse angle (δ):
Round to    decimal places.



Formulas:
b = √ d² - (a-c)²
d = √ (a-c)² + b²
e = √ a² + b²
f = √ c² + b²
m = ( a + c ) / 2
p = a + b + c + d
A = 1/2 * b * ( a + c )
α = 90° - arccos( ( b² + d² - (a-c)² ) / ( 2 * b * d ) )
δ = 180° - α

Side lengths, diagonals and perimeter have the same unit (e.g. meter), the area has this unit squared (e.g. square meter).
