Are the diagonals of a rectangle are equal in length?
The diagonals of a rectangle have another important property − they are equal in length. The proof has been set out in full as an example, because the overlapping congruent triangles can be confusing. The diagonals of a rectangle are equal.
Who have diagonals of equal length?
Properties of the diagonals in some quadrilaterals

What is the name of an equilateral rectangle?
|Equilateral triangle or rectangle, e.g.|
Do all rectangles have the same length?
Opposite sides of a rectangle are the same length (congruent). The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a “right angle.” So, a rectangle has four right angles.
What is true for all rectangles?
All rectangles are made up of right-angled triangles. The angles of a rectangle are all congruent. The diagonals of a rectangle intersect in a right angle. A rectangle has one pair of opposite sides of equal length.
Which shape has more sides?
|Triangle – 3 Sides||Square – 4 Sides|
|Pentagon – 5 Sides||Hexagon – 6 sides|
|Heptagon – 7 Sides||Octagon – 8 Sides|
|Nonagon – 9 Sides||Decagon – 10 Sides|
