Answer:
This is an acute, scalene triangle.
Explanation:
Alright, to find the type of triangle, let's use the distance formula (to find the length of the sides). 
d = 

The distance from (2,3) to (5,0) is 
 . = 4.24264068
. = 4.24264068
The distance from (2,3) to (4,4) is 
 . = 2.23606797
. = 2.23606797
The distance from (5,0) to (4,4) is 
 . = 4.12310562
 . = 4.12310562
The length that is longest is 
 .
. 
Let's label it c. 
Let's label the distance from (2,3) to (4,4) a.
Let's label the distance from (5,0) to (4,4) b.
If c^2 = a^2+b^2, this is a right triangle. 
If c^2 < a^2+b^2, this is an acute triangle. 
If c^2> a^2+b^2, this is an obtuse triangle.

18 vs 22. 
c^2 < a^2 + b^2. 
This is an acute triangle. 
None of the sides are equal, so this is a scalene triangle.
