Trapezoid Properties and Calculations
This page delves deeper into the properties of trapezoids, focusing on the isosceles trapezoid trapezroˊwnoramienny and providing essential formulas for area calculations.
Definition: An isosceles trapezoid is a trapezoid where the non-parallel sides legs are of equal length.
Key properties of isosceles trapezoids include:
- Equal leg lengths: |AE| = |ED|
- Equal base angles
- Diagonals of equal length: |BF| = |FC|

Example: In an isosceles trapezoid, if one base angle is 60°, the other base angle on the same side will also be 60°, as they are equal in an isosceles trapezoid.
The page also presents the formula for calculating the area of a trapezoid:
Area = (a+b / 2) * h
Where:
- a and b are the lengths of the parallel sides
- h is the height of the trapezoid
