Right Trapezoid Calculator

A right trapezoid is a trapezoid with one of its legs perpendicular to both of the bases. In other words, it means that such a trapezoid must contain two right angles.

It should be our favorite type of trapezoids — it's much easier to calculate! This is because the height of the trapezoid is equal to one of its sides.

Don't you worry — our right trapezoid calculator is here to help you with all the necessary steps. 👌 We'll calculate:

• Right trapezoid area;
• Right trapezoid slant side;
• Right trapezoid height;
• Right trapezoid perimeter;
• Right trapezoid angles; and
• Right trapezoid median — available in the median section of the calculator.

💡 A rectangle is also a right trapezoid — it does satisfy the condition described above!

We can easily calculate the slant side of a right angle trapezoid using the Pythagorean theorem:

d = √[(a − b)² + c ²]

where:

• d — Slant (long) side of a trapezoid;
• a — Longer base;
• b — Shorter base; and
• c — Short side (trapezoid's height).

A right trapezoid is indeed special - its height is equal to the length of its shorter side. We can calculate it easily using a modification of the Pythagorean theorem:

b = √[d² − (a − c)²]

where:

• b — Shorter base;
• d — Slant (long) side of a trapezoid;
• a — Longer base; and
• c — Short side (trapezoid's height).
