Diagonal properties of a rectangle2/27/2024 ![]() Note that the tick marks are all the same, which tells us that all the sides are the same length. It has all the properties of the parallelogram but all of the sides of a rhombus are congruent. Properties of a RhombusĪnother special parallelogram is a rhombus. In fact, they are all right angles, which means they measure 90 degrees. ![]() What makes a rectangle a special parallelogram is that its interior angles are the same. That means that the opposite sides are both parallel and congruent, just like our first parallelogram. But one thing we don’t usually think about is that rectangles are just a special kind of parallelogram. The opposite sides of a parallelogram, marked by green tick marks, are congruent, which means they have the same measure.Ī rectangle is a shape we all know well since it appears in the real world so often. The blue arrows denote which sides are parallel to each other. Types of Quadrilaterals Properties of a ParallelogramĪ parallelogram is a quadrilateral that has two sets of parallel sides. A polygon is a shape with multiple sides. Let’s get started!Īll of the shapes that we are going to look at today are quadrilaterals, meaning they are all four-sided polygons. Hi, and welcome to this video on diagonals! Today we’re going to explore the diagonals of parallelograms, rectangles, rhombi, and squares, and see how these shapes relate to each other overall.
