Since $\angle IAB=\angle ICB$, and $\angle IBA=\angle IBC$, their remaining angles must be equal. MEDIUM. The diagonals of a rhombus are the lines that connect the opposite vertices (corners) in the center of the shape. You can use these properties in the following practice geometry questions, first, to solve for a missing variable x, and […] The gradients of the diagonals are $$m_1 = \frac{q}{p+b}, \ \ \ m_2 = \frac{q}{p-b}$$. View Answer. For example, all of its sides are congruent, and it contains diagonals that are perpendicular bisectors and that bisect the angles of the rhombus. The diagonals of rhombuses also form four right triangles, with hypotenuses equal to the side length of the rhombus and legs equal to one-half the lengths of the diagonals.

Area of a Rhombus = 1/2 x 12 x √ ((4 x 7 2) - 12 2) = 6 x √52 Once you have one diagonal length, divide that in half to get each half of the diagonal separately. Suppose that angle at D is $x.$ Then the diagonal length is $$6\sqrt{2-2\cos x}=12\sin(x/2).$$ Here, $x=100^{\circ}.$ There is no nice value for $\sin (50^{\circ})$ - the best answer for the diagonal length is $12\sin (50^{\circ})$ and trig ratios are inherently involved. If you draw the two diagonals, you can by angle-chasing show that the four triangles so formed are all congruent. A rhombus is a type of Parallelogram only. That means, a = 10cm. Use MathJax to format equations. The diagonals of rhombus are 20 cm and 48 cm respectively then find the side of the rhombus. We give a traditional "angle-chasing" argument.
