\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 1}}\quad ,&{{ 4}})\quad % (c,d) &({{ -2}}\quad ,&{{ -1}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2} \\\\\\ d=√((-2-1)^2+(-1-4)^2)\implies d=√((-3)^2+(-5)^2) \\\\\\ d=√(9+25)\implies d=√(34)
