Question

prove that area of triangle with (t,t-2) , (t+2, t+2) and ( t+3, t) is independent of t​

Answer 1

Step-by-step explanation:

1/2* t(t+2-t)+t+2(t-t-2)+t+3(t-2-t+2)

1/2*2t+(-2t)-4+0

1/2*(-4)

=(-2)

:.Therefore area of triangle is independent of t.

Answer 2

Answer:

1/2* t(t+2-t)+t+2(t-t-2)+t+3(t-2-t+2)

1/2*2t+(-2t)-4+0

1/2*(-4)

=(-2)

:.Therefore area of triangle is independent of t.
