A line segment joining one corner to another but is not an edge is called a diagonal. In other words, a diagonal is a line that connects the opposite vertices of a polygon. Learn the definition, formula, examples & practice questions.
of vertices. For instance, in square ABCD, diagonals will connect A to C and B to D. Pentagons will always have five diagonals that create a star-shaped pattern with a smaller pentagon in the center. The shape of the polygon and its number of diagonals are not related. That is, even...
Through the above formula we can see that if are given the side of a regular pentagon, we can find its area. Let us consider the example that we discussed above where we calculated the area of a pentagon having a side of 4 cm. We shall now see how this operation can be performed us...
Regular Pentagon:A pentagon is a polygon made up of five line segments that are connected to each other. A regular pentagon is made of five line segments that are of equal length. The diagonal can be computed by the formula below where {eq}a {/eq} is the length of ...
Case 1:Diagonal formula in terms of cosine Beta angle M = √ (a2+ b2- 2abcosβ) N = √ (a2+ b2+ 2abcosβ) ADVERTISEMENT Case 2:Diagonal formula in terms of cosine Alpha angle M = √ (a2+ b2- 2abcosα) N = √ (a2+ b2+ 2abcosα) ...
