Question

15. Without using Pythagoras theorem, show that the
points A (0,4), B (1, 2) and C (3,3) are the vertices
of a right angled triangle.​

Answer 1

Step-by-step explanation:

M of AB = 2-4/1-0

=-2

M of BC =3-2/3-1

= 1/2

Now Mab × Mbc = -2 × 1/2 = -1

Hence , Line AB & BC is perpendicular to each other. It is right angle triangle
