How Many Diagonals Does a Rectangle Have

Introduction

In geometry, the components of a shape are diagonals. A diagonal in mathematics is a line that joins two solids or polygons whose vertices are not on the same edge. A diagonal is typically thought of as a sloping or slanting line that joins the vertices of a shape. The term "diagonal" refers to lateral shapes with sides, edges, and corners. For curved shapes like circles, spheres, cones, etc., we can find diagonals. The Greek word "diagonios," which means "from angle to angle," is the source of the English word "diagonal." Additionally, in matrix algebra, the set of entities from one corner to the farthest corner is defined by the diagonal of the square matrix.

Diagonal of Rectangle

A line segment that connects any two of a rectangle's non-adjacent vertices is said to be its diagonal. Two diagonals divide a rectangle into two right-angled triangles, with the diagonal serving as the hypotenuse on each diagonal. The diagonals cut each other in half, creating an acute angle and an obtuse angle on each side. The diagonal of the rectangle forms two congruent triangles.

Diagonal of Rectangle Formula

Finding the rectangle's length and width is made easier by using the diagonal of a rectangle formula. If we are having a rectangle ABCD, with AC and BD the diagonals. We can see that the lengths of both diagonals AC and BD are the same. A diagonal divides a rectangle into two right triangles with hypotenuses that are the same length as the sides of the rectangle. The diagonal is the hypotenuse there. Thus, to calculate the length of diagonals of a rectangle the formula will be - d=\sqrt{(l^{2}+w^{2})} , where d = diagonal of rectangle, l = length, w = width.

Properties - Diagonal of Rectangle

A line segment that connects the diagonal vertices of a rectangle is drawn between their opposing vertices. The properties of the diagonals of a rectangle are as follows:

• The length of the two diagonals in a rectangle is equal and they are congruent.

• The rectangle is divided into two equal parts by the intersection of the two diagonals.

• By applying the Pythagorean theorem, one can determine the length of a rectangle's diagonal.

• A rectangle's centre angles become one obtuse angle and one acute angle when the diagonals cut each other in half.

• A square is formed when two diagonals split in half at an angle of 90 degrees.

• The diagonal of a rectangle is regarded as the hypotenuse of the two right-angled triangles that result from the division of the rectangle into this diagonal.

Conclusion

Therefore, from above we can conclude that a rectangle has two diagonals as it has four sides.
