Question

Find the measure of each side of the triangle JKL
J (9,9) K (12,14) L(14,6)
How would I do this can some one just give me a example of how to do one?

Answer 1

\(\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
J&({\color{red}{ 9}}\quad ,&{\color{blue}{ 9}})\quad K&({\color{red}{ 12}}\quad ,&{\color{blue}{ 14}})\\
K&({\color{red}{ 12}}\quad ,&{\color{blue}{ 14}})\quad L&({\color{red}{ 14}}\quad ,&{\color{blue}{ 6}})\\
L&({\color{red}{ 14}}\quad ,&{\color{blue}{ 6}})\quad J&({\color{red}{ 9}}\quad ,&{\color{blue}{ 9}})
\end{array}\qquad
d = \sqrt{({\color{red}{ x_2}}-{\color{red}{ x_1}})^2 + ({\color{blue}{ y_2}}-{\color{blue}{ y_1}})^2}\)
