A cube is a three-dimensional solid figure, also known as a square solid that has edges of the same length. This means that the length, width, and height of a cube are equal, and all its faces are squares. The body diagonal of a cube is the line segment that cuts through its center, joining the opposite vertices. While the face diagonal is the one ...
A cuboid is a three-dimensional form of a rectangle. The body diagonal of a cuboidis the one that cuts through the center of the cuboid; while the face diagonal is the one joining the opposite vertices on every face. The number of diagonals in a polygon differs according to the type of polygon, based on the number of sides. The formula that is used...
The length of the diagonal of a square can be calculated using the Pythagoras theorem. Since the diagonal of a square divides the square into two right-angled triangles, the diagonal acts as a hypotenuse. So, applying the Pythagoras theorem, we can find the diagonal length using the formula, Diagonal (d) = √(x2 + x2); where 'd' is the diagonal, and...
The length of a diagonal of a rectangle can be calculated using the Pythagoras theorem because the diagonal of a rectangle divides the rectangle into two right-angled triangles. So, the diagonal acts as the hypotenuse, and the formula that is derived is, d2 = l2 + w2. This further makes it, Length of a diagonal of a rectangle (d) = √(l2 + w2); wher...
A cube has 6 faces and each face of a cube is a square. Thus, each face has two diagonals. Consider a cube of length x units. So, using the Pythagoras theorem, the length of each face diagonal of cube = √2x Apart from the diagonals on the faces, there are 4 other diagonals (body diagonals) that pass through the center of the square. The formula for...
Consider a cuboid of length l, width w, and height h. Let us assume that its body diagonal that passes through the center of the cuboid is 'd'. Length of the body diagonal of a cuboid = √(l2 + w2 + h2). Important Notes on Diagonals 1. The number of diagonals of a polygon can be calculated with the formula, Number of diagonals = n(n - 3)/2; where 'n...
A diagonal is a line segment connecting the opposite vertices (or corners) of a polygon. In other words, a diagonal is a line segment connecting two non-adjacent vertices of a polygon. It joins the vertices of a polygon, excluding the edges of the figure.

Aug 3, 2023 · The diagonal of a polygon is the line segment that links the opposite, nonadjacent corners or vertices of that polygon. How Many Diagonals are there in a Polygon. Diagonal of Polygon. How to Find the Number of Diagonals in a Regular Polygon. For an n -sided regular polygon, the number of diagonals can be obtained using the formula given below:
A diagonal of a polygon is a line segment joining two vertices. From any given vertex, there is no diagonal to the vertex on either side of it, since that would lay on top of a side. Also, there is obviously no diagonal from a vertex back to itself.
6 days ago · A diagonal is a segment of a polygon that connects two non-consecutive vertices. In a polygon, the number of diagonals that can be drawn from any vertex is three less than the number of sides.
