Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7).
LuckyWell [14K]

Answer: See below

Step-by-step explanation:

Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7)

A)

\begin{aligned}&A B=\sqrt{(2-0)^{2}+(5-2)^{2}}=\sqrt{13} \\&B C=\sqrt{(-1-2)^{2}+(7-5)^{2}}=\sqrt{13} \\&C A=\sqrt{(-1-0)^{2}+(7-2)^{2}}=\sqrt{26} \\&A B=\sqrt{13}, B C=A B=\sqrt{13}, C A=\sqrt{26}\end{aligned}

B) Slope of AB line = m₁=3/2

Slope of BC line = m₂=-2/3

Slope of CA line = m₃=-5

C) \mathrm{AB}=\mathrm{BC} \& \mathrm{AB}^{2}+\mathrm{BC}^{2}=\mathrm{CA}^{2}

Therefore, the triangle is a isosceles right angle triangle

In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.
Mnenie [13.5K]

<u>Answer:</u>

The correct answer option for this is: False.

<u>Step-by-step explanation:</u>

We are given the following statement which we are to determine whether its true or false:

<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>

To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.

While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
