Question

Prove that the points (2,4), (6,4), and (6, 7) form a right angled triangle.​

Answer 1

Answer:

distance between two points : ((x2-x1)²+(y2-y1)²)^0.5

by this formula we get distance between :1st and 2nd point distance is 4

distance between :2nd and 3rd point distance is 3

distance between :1st and 3rd point distance is 5

by pythagoras rule 3²+4² = 5²

hence distances satisfy pythagoras rule

so the points form a righ angled triangle
