Geometry 6.5b, Apply & Identify Special Parallelograms in the Coordinate plane

Показать описание

(Sorry, ERROR AT 4:21, it should be BD and not BC, we're finding the diagonals) An explanation of how we can prove that a given quadrilateral is a rectangle, rhombus, or square by using the definitions of the special quadrilaterals. We apply the conditions for special parallelograms to determine if a conclusion is valid, we identify special parallelograms in the coordinate plane using diagonals to determine whether a parallelogram with given vertices is a rectangle, rhombus, or square. We use the Distance Formula and the Slope Formula to help us do this.
