prove that the points (2,-2),(-2,1) and (5,2) are the vertices of a right angled triangle. also find the area of this triangle

1st use distance formula for each side of the triangle

then use PT for checking if they are equal then u will get it as equal

then use area of triangle formula u will get the ans explanation:

c
