Please solve question no.14.

Dear Student.

A B = \sqrt{{(6 - 3)}^{3} + {(4 - 1)}^{2}} = \sqrt{3^{2} + 3^{2}} = 3 \sqrt{2} u n i t s B C = \sqrt{{(8 - 6)}^{2} + {(6 - 4)}^{2}} = \sqrt{2^{2} + 2^{2}} = 2 \sqrt{2} u n i t s A C = \sqrt{{(8 - 3)}^{2} + {(6 - 1)}^{2}} = \sqrt{5^{2} + 5^{2}} = 5 \sqrt{2} u n i t s S i n c e A B + B C = A C H i n c e p o i n t B l i e s o n A C T h u s A, B, C a r e c o l l i n e a r
