A trapezoid is a quadrilateral with one pair of opposite parallel sides, known as the bases and the other two as the lateral sides. It is a clo and its perimeter is calculated using the formula Perimeter = sum of all sides of the isosceles trapezoid. An isosceles trapezoid has congruent base angles and non-parallel sides that add up to 360 degrees. The median runs parallel to both bases and its length is equal to the sum of the bases’.
The trapezoid has an axis of symmetry, with the line of symmetry going through the midpoints of the bases. However, it lacks rotational symmetry, except in rectangles. The sum of the interior angles in an isosceles trapezoid is 360 degrees.
Isosceles trapezoids have supplementary angles opposite one another, or add up to 360 degrees. The slope of an isosceles trapezoid makes an angle of 45° with the base, and the area of an isosceles trapezoid is 360 degrees.
The formula for calculating the area of an isosceles trapezoid is Area = (sum of parallel sides ÷ 2) × height. In the isosceles triangle PTS, the two adjacent angles are 35°, so the third angle is 110° and then 65°. The sum of the interior angles of an isosceles trapezoid is always 360 degrees, just like any quadrilateral.

what if you are given an isosceles trapezoid and you have to find the area, but the variables given, in regards to the parallel sides, the longer base and height. No other information regarding other sides, angles, or diagonals are given. How do you find the missing base? or the area? Once the missing base is found I know the formula for area. A=(1/2)(b1+b2)(h)
