Question

Prove that the points (2,3),(-4,-6)and(1,3/2) do not form a triangle

Answer 1

Answer:

STEP 1) MARK POINT 2,3 ON GRAPH PAPER AS POINT A

STEP 2) MARK POINT -4,-6 ON GRAPH PAPER AS POINT B

STEP 3) MARK POINT 1,3/2 i.e. 1,1.5 ON GRAPH PAPER AS POINT C

STEP 4) JOIN ALL THE POINTS, WE GET A STRAIGHT LINE PQ.

.

SO, THESE POINTS CAN'T MAKE A TRIANGLE AS THEY MUST BE NON - Collinear TO FORM A ∆ BUT ALL POINTS LIE IN A STRAIGHT LINE i.e. THEY ARE COLLINEAR.
