Answer 1

Answer:

the area formed by the three points must be zero

Step-by-step explanation:

since the three points are collinear they dont form a triangle at all ao the area formed by the ∆ is zero

another two conditions can also be considered such as

slope and length

Answer 2

Answer:

Since the three point are collinear they don't form a triangle at all so that area formed by angle is zero

another

two conditions can also be considered such as slope and length
