Question

The points A(2,2),B(1,2) and C(3,5) are vertices of a 
  1. acute angle triangle
  2. right angle triangle
  3. obtuse angle triangle
  4. equilateral triangle


Solution

The correct option is B right angle triangle
Given points are A(2,2),B(1,2) and C(3,5)
Side lengths are
AB=(2+1)2+(22)2=5 unitsBC=(13)2+(25)2=5 unitsAC=(23)2+(25)2=52 units
By observation we write
AB2+BC2=AC2
So, ABC is right angle triangle.
