Properties and Relationships of Quadrilaterals

This video tutorial covers the properties of squares, highlighting their classification as special parallelograms. It explains how squares share properties with parallelograms, rectangles, and rhombuses, including having four right angles and congruent sides. The video demonstrates the congruence and perpendicularity of square diagonals using distance, slope, and midpoint formulas. A two-column proof is presented to show that a triangle within a rectangle is isosceles. The tutorial concludes with a summary of quadrilateral properties and a preview of the next lesson on constructing a rhombus.
