A quadrilateral having opposite sides equal and each angles 90° (right angle) is called a rectangle. Or, we can say, a rectangle is a parallelogram with each angle 90°. So, each rectangles are parallelograms but each parallelograms are not rectangles.
What is a rectangle in geometry with diagram - find out its definition and properties with calculation of diagonal, area and perimeter using formulas

Topic for February 28, 2015: Solving for the angles that the diagonal make with the faces of a rectangular parallelepiped. Please visit the website to see the details. If you have any questions, please send me an e-mail.
Practice finding the area of rectangles and parallelograms with a worksheet that adds a coordinate-plane twist! Instead of simply giving students a figure with its dimensions labeled, students first graph the vertices from ordered pairs and then determine the area of the figure they created.The worksheet includes 9 problems featuring rectangles and parallelograms in a variety of sizes, positions, and orientations on the coordinate plane. This gives students practice with the familiar area skills from a geometry or measurement unit while incorporating coordinate graphing and ordered pairs.Skills Practiced:Finding the area of rectanglesFinding the area of parallelogramsUsing base and height to calculate areaPlotting ordered pairsGraphing figures on the coordinate planeDetermining dimensions

Area of rectangles, parallelograms and triangles









Parallelogram
In elementary geometry, two of the most fundamental quadrilaterals are the square and the rectangle. Both fall under the family of parallelograms, sharing several properties such as having four right angles and opposite sides equal and parallel. However, they also have distinct characteristics that make them unique. #Square #Rectangle
