Chapter 13: Q. 13 (page 526)

Given points A, B, and C. Find AB, BC, and AC. Are A, B, and C collinear?
If so, which point lies between the other two?
13. A(0, 3), B(-2, 1), C(3, 6)

Short Answer

Expert verified

The values of $A B = 2 \sqrt{2}, B C = 5 \sqrt{2}, A C = 3 \sqrt{2}$ .

A, B, Care collinear.

PointA lies between the other two points.

Step by step solution

Step-1 – Given

The given points are $A (0, 3), B (鈭� 2, 1), C (3, 6)$

Step-2 – To determine

We have to find the lengths AB, BCand AC.Then have to check ifA, B, C are collinear. And determine that which point lies between the other two.

Step-3 – Calculation

Using the distance formula, the distance between A and B is:

$\begin{array}{l} A B = \sqrt{{(鈭� 2 鈭� 0)}^{2} + {(1 鈭� 3)}^{2}} \\ A B = \sqrt{{(鈭� 2)}^{2} + {(鈭� 2)}^{2}} \\ A B = \sqrt{4 + 4} \\ A B = \sqrt{8} \\ A B = 2 \sqrt{2} \end{array}$

Using the distance formula, the distance between B and C is:

$\begin{array}{l} B C = \sqrt{{(3 鈭� (鈭� 2))}^{2} + {(6 鈭� 1)}^{2}} \\ B C = \sqrt{{(3 + 2)}^{2} + {(6 鈭� 1)}^{2}} \\ B C = \sqrt{{(5)}^{2} + {(5)}^{2}} \\ B C = \sqrt{25 + 25} \\ B C = \sqrt{50} \\ B C = 5 \sqrt{2} \end{array}$

Using the distance formula, the distance between A and C is:

$\begin{array}{l} A C = \sqrt{{(3 鈭� 0)}^{2} + {(6 鈭� 3)}^{2}} \\ A C = \sqrt{{(3)}^{2} + {(3)}^{2}} \\ A C = \sqrt{9 + 9} \\ A C = \sqrt{18} \\ A C = 3 \sqrt{2} \end{array}$

Hence,

$\begin{array}{l} A B + A C = B C \\ B C = 2 \sqrt{2} + 3 \sqrt{2} \\ B C = 5 \sqrt{2} \end{array}$

So, the values of $A B = 2 \sqrt{2}, B C = 5 \sqrt{2}, A C = 3 \sqrt{2} .$

A, B, Care collinear.

PointA lies between the other two points.
