Given:  Isosceles trapezoid

Find:  The perimeter of

To find:
The perimeter of the isosceles trapezoid
Definition:
The perimeter of any closed figure is given by the sum of all the lengths of its boundary.
Calculation:
Given,
An isosceles trapezoid
The bisectors of
In the above given isosceles trapezoid, we have the following congruent measurement.
A pair of the nonparallel sides of any isosceles trapezoid is congruent.
Each pair of base angles are congruent.
Thus,
Also
Since, the above congruent angles
In a trapezoid sum of the adjacent angles which lie on the opposite bases is
Add;
Thus,
Also,
By the property that the sum of all the three inferior angle of any triangle is
In
Thus,
Also, in
Thus,
Further, in
Thus,
Now consider the
Since,
Thus, we have two right triangle
In
By the application of
