If the vertices of $\Delta PQR$ are $P(3, 10)$,$Q(6, 5)$,and $R(1, 2)$,then $\Delta PQR$ is a $\dots$ triangle.

Name the type of triangle formed by the points $A (-5, 6)$,$B (-4, -2)$,and $C (7, 5)$.

Area of $\Delta ABC$ is $\frac{3}{2}$. The $Y$-coordinate of its centroid is $8$ less than three times its $X$-coordinate. If $A$ is $(2, -3)$ and $B$ is $(3, -2)$,find the coordinates of $C$.

If the distance between the points $(a, 1)$ and $(8, a)$ is $5,$ then $a=$

$P(3, 2)$ and $Q(7, k)$ are the given points. If $d(P, Q) = 5$,then $k = \dots \dots \dots$

$P(0, 1/2)$,$Q(1/2, 1/2)$,and $R(1/2, 0)$ are respectively the midpoints of sides $\overline{AB}$,$\overline{BC}$,and $\overline{CA}$ in $\Delta ABC$. Find the coordinates of $A$,$B$,and $C$.
