Solution : To show that the given points forms a square we need to find the distance between the given points. A rhombus is a type of parallelogram. Found 2 solutions by Edwin McCravy, KMST: Solution. Find an answer to your question A (-3,4) and c (2,-6) are the opposite vertices of a rhombus. A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent.. As we know that the diagonals of rhombus are equal in length & intersect each other normally. What is the area of the kite? The diagonals of a rhombus are 12 in. Graph of the rhombus … Consider the Δ ADC. Is this the reason we have taken (4,-3) as points ? Here is the link for understanding how to do it with an example. One unusual quality of a rhombus is that its diagonals are always perpendicular to each other, no matter the angles of the rhombus's four vertices. (6)  If opposite angles of a rhombus are (2x)Â° and (3x-40)Â° then value of x is ? $$\sqrt{(x-0)^2+(y-0)^2}=5 \implies x^2+y^2=25$$ Setting the value of $y$, we get $$x^2+\left(-\frac{3}{4}x\right)^2=25 \implies x^2=16 \implies x=\pm 4$$$$x=4\quad \implies y=-\frac{3}{4}(4)=-3$$ $$x=-4\quad \implies y=-\frac{3}{4}(-4)=3$$ Thus, all the unknown vertices of rhombus ABCD are $B\equiv (4, -3)$, $C\equiv(-3, -4)$ & $D\equiv(-4, 3)$. And just to make things clear, some rhombuses are squares, but not all of them. If the area of a rhombus is 10 sq.unit . Solution, (6)  If opposite angles of a rhombus are (2x)Â° and (3x-40)Â° then value of x is ? Use MathJax to format equations. Solution, (10)  The diagonals of a rhombus are 12 in. Let the radius of the circle be r. Since, all the vertices of a rhombus lie on a circle that means each diagonal of a rhombus must pass through the centre of a circle that is why both diagonals are equal and same as the diameter of the given circle. It's diagonals intersect at (0,0) if one vertex of the rhombus is (3,4) , then one of the other vertices can be ? The opposite angles are congruent their arcs will be congruent. since both the diagonals are equal , it is a square. Find the values of p and q. A (2, -3), B (6, 5),  C (-2, 1) and D (-6, -7), (2)  Three vertices of a rhombus taken in order are, (3)  Assume quadrilateral EFGH is a rhombus.
