The Coordinates of the given triangles are A) (2, -2)(7, -2)(2, 5) B) (2, -2)(8, -2)(2, 5) C) (2, -2)(7, -2)(2, 6) D) (2, -2)(8, -2)(2, 6) .
Using distance formula between two points we can find the length of sides of the triangle.
Distance between 
The two triangles are similar by following criterion
1.AA or AAA 2.SSS 3. SAS Where A=angle ,S=side, Sides must be proportional
In the four triangles given neither two of them satisfies the above criteria .
So No two of them are similar to each other.
