Rectangles are a special type of parallelogram, in which all the interior angles measure 90°. Because all rectangles are also parallelograms, all the properties of parallelograms are also true for … [Read more...] about Rectangles: the Diagonals are of Equal Length
A parallelogram in which all the angles are right angles is called a rectangle.
Since a general property of all parallelograms is that all adjacent angles are supplementary (add up to 180°), it is obvious that if a parallelogram has one right angle (90°), then all the other angles are also 90°
In addition to the general properties of parallelograms, in a rectangle, the diagonals are of equal length,
We will show these properties using triangle congruence.
Now that we've explained the basic concept of rectangles in geometry, let's scroll down to work on specific geometry problems relating to this topic.
