Intro to Parallelograms
Welcome to this video lesson on common quadrilaterals.
Today, we will go over parallelograms, rectangles, and squares.
a) parallelogram = A parallelogram is a quadrilateral where all opposite sides are parallel and of equal length, and all opposite angles are equal.
To find the area of a parallelogram, multiply the length of on the the sides, and multiply it by the height. In this case: x times h = area.
b) rectangle = A rectangle is a quadrilateral where all angles are equal to 90º, and all opposite sides are of equal length. The area of a rectangle is very easy to find, just like a parallelogram, height times width, in this case, x times y.
c) square = A square is a quadrilateral where all side lengths and angle measures are equal. Since all sides are equal, finding the area is simply a matter of multiplying any side by itself.
I hope that helps. Thanks for watching this video lesson, and until next time, happy studying.
