The Total solution for NCERT class 6-12
Check whether (5, тАУ 2), (6, 4) and (7, тАУ 2) are the vertices of an isosceles triangle.
Since two sides of any isosceles triangle areequal. To check whether given points are vertices of an isosceles triangle, wewill find the distance between all the points.
This implies, whether given points arevertices of an isosceles triangle.
