Express the relationship between the number of sides of a polygon to the number of diagonal of a polygon?
n*(n-3)/2 where n- no. of sides
How do you work out the diameter of a rectangle?
The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.
What has Diagonal that bisect opposite angles?
A square, a rhombus or s kite would fit the given description
How do I find a missing diagonal in a rhombus?
The answer depends on what information you do have about the rhombus. Assuming that you know the length of the sides and one of the diagonals, then,In the triangle formed by the given diagonal and the sides of the rhombus, you know all three sides. So you can use the cosine rule to calculate the angle between the sides of the rhombus.The other pair of angles in the rhombus are its supplement.So now you know two sides and the included angle of the triangle formed by the missing diagonal and the sides of the rhombus.You can use the cosine rule again to find the missing diagonal.
Is the diagonal of a square irrational?
Not necessarily. If the sides are a multiple of sqrt(2) units, then the diagonal is rational.
How do you calculate the sides of a parallelogram given the height and longer diagonal?
The height and longer diagonal do not provide enough information to calculate the sides.
What is the number of diagonal from one vertex if there are 6 sides?
There are 4
What makes a quadrilateral unique?
4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.
Express the relationship between the number of sides of a polygon to the number of diagonal of a polygon?
n*(n-3)/2 where n- no. of sides
What is the formula for area of quadrilateral when 4 sides of it are given?
With four sides given a quadrilateral is not clear defined. Infinite are possible. You need the length of one diagonal in addition to figure out the area.

On the right angle how do you get the diagonal if the two sides of triangle are given?
Use the Pythagorean theorem, which is a2+b2=c2.
How many diagonal sides does a rectangle have?
A diagonal cannot be a side of a rectangle, and a side cannot be a diagonal.
Do parallelograms have diagonal sides?
A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.
What is the formula of diagonal lines?
The formula is: 0.5*(n^2 -3n) = number of diagonal lines whereas 'n' is the number of sides of the polygon
What is the formula to find the diagonal of parallelogram?
0.5*(n2-3n) where n equals the number of sides of the polygon
