# how to find the vertices of a rhombus

Putting in the distance you have $t = 1/5$. Since, the semi-diagonal OB is normal to OA, we get $$\left(\frac{y-0}{x-0}\right)\left(\frac{4-0}{3-0}\right)=-1 \implies y=-\frac{3}{4}x \tag 1$$ Since $OB=OA=\sqrt{3^2+4^2}=5$, we get I found out C as(-3,-4) . @Nancy Yes, as Alexey also mentions this is required for orthogonality. No, just show the diagonals are perpendicular or two consecutive sides are congruent. Note: I keep coming up with an answer that doesn't make sense, the other problems, no problem.
