Chapter 13: Q. 15 (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?
15. A(-5, 6), B(0, 2), C(3, 0)

Short Answer

Expert verified

The values of $A B = \sqrt{41}, B C = \sqrt{13}, A C = 10$ .

A, B, Care not collinear.

Step by step solution

Step-1 – Given

The given points are $A (鈭� 5, 6), B (0, 2), C (3, 0)$ .

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:

$\begin{array}{l} A B = \sqrt{{(0 鈭� (鈭� 5))}^{2} + {(2 鈭� 6)}^{2}} \\ A B = \sqrt{{(0 + 5)}^{2} + {(2 鈭� 6)}^{2}} \\ A B = \sqrt{{(5)}^{2} + {(鈭� 4)}^{2}} \\ A B = \sqrt{25 + 16} \\ A B = \sqrt{41} \end{array}$

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

$\begin{array}{l} B C = \sqrt{{(3 鈭� 0)}^{2} + {(0 鈭� 2)}^{2}} \\ B C = \sqrt{{(3)}^{2} + {(鈭� 2)}^{2}} \\ B C = \sqrt{9 + 4} \\ B C = \sqrt{13} \end{array}$

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

$\begin{array}{l} A C = \sqrt{{(3 鈭� (鈭� 5))}^{2} + {(0 鈭� 6)}^{2}} \\ A C = \sqrt{{(3 + 5)}^{2} + {(0 鈭� 6)}^{2}} \\ A C = \sqrt{{(8)}^{2} + {(鈭� 6)}^{2}} \\ A C = \sqrt{64 + 36} \\ A C = \sqrt{100} \\ A C = 10 \end{array}$

Note that the sum of any two lines is not equal to length of other line.

So, A, B, Care not collinear.

The values of $A B = \sqrt{41}, B C = \sqrt{13}, A C = 10$ .
