of a triangle are non-collinear.
​

Answer 1

Answer:

HI MATE !

➨ Triangle is one of the basic shape in geometry. A triangle is a simple closed figure made up of three line segments. It has three sides and three vertices. It is represented by the symbol ∆. But in the figure, only two points A and D lied on the line. Points B, E, C and F do not lie on that line. Hence, these points A, B, C, D, E, F are called non - collinear points.

So,

➨ Your answer is The three angles of a triangle are non-collinear.

Answer 2

Step-by-step explanation:

1Distance= area under graph = area of five parts under graph =

×1×40

Distance=20+40+20+10+20=110m

Displacement = area above x axis −area under x axis =90−20=70m

Hence,

option (B) is correct answer
