Thus diagonals of a rectangle are of equal length and bisect each other. Hence, diagonals of a rectangle are of equal length.įrom the property of a parallelogram the diagonals of a rectangle bisect each other at their intersection point. Triangles ABD and ADC are Right Angled Triangles right angled at L DAC and L ADC respectively. ![]() Diagonals of a rectangle are equal.Ĭonsider two Triangles ABD and ADC containing two diagonals BD and AC respectively. Hence, all angles in a rectangle are equal to 90 degrees. Hence, by the Sum of angles property in a parallel lines,Īgain, by the property of parallelogram that opposite angles are equal, Since opposite angles in a parallelogram are equal, we have If in a parallelogram one angle is 90 degrees then all angles are 90 degrees.Ĭonsider a parallelogram ABCD, where it is given that L BCD = 90°. The corner angles all are right angles (90°).ģ. To draw rectangles, you need a Graphics object and a. The rectangle has following special properties:ġ. A rectangle is defined by its Width, Height, and upper-left corner represented by the Location property. Diagonals of a parallelogram bisect each other in their intersection point. Opposite angles of a parallelogram are equal.ģ. ![]() Opposite sides of a parallelogram are equal.Ģ. The properties of a Parallelogram common to rectangle are:ġ. Hence a rectangle has all the properties of a parallelogram. Further we are going to build a deep understanding of their properties and will prove them simultaneously.Ī parallelogram in which each angle is 90 degrees is called a rectangle. In this lesson we are going to deal with rectangles and their basic properties. A rectangle is one of the most commonly known quadrilaterals. ![]()
