A trapezoid is a quadrilateral with one pair of parallel sides. The other two sides, known as the legs, are not parallel. The base angles of a trapezoid are the angles formed between the legs and the base. These are the angles we will be focusing on in our calculations.

## Trapezoid Formulas

• Area = h(a+b)/2
• Perimeter = a + b + c + d
• Diagonal L1H2 = sqrt(h2+(b-sqrt(c2-h2))2)
• Diagonal H1L2 = sqrt(h2+(b-sqrt(d2-h2))2)
• For example, When Parallel Side a =4, b = 5, Angle (θ) = 0.9273, Angle (Φ) = 0.6082, altitude(h) = 5, Then the area= 22.5, perimeter = 24.000550386222713, Side c = 6.25, side d = 8.7506, Diagonal L1H2 = 5.1539, Diagonal H1L2 = 5.4551.
