Answer 1

Answer:

the triangle formed is scalen triangle

Step-by-step explanation:

let A, B, C is a triangle

Answer 2

Right angle triangle  and also scalene triangle

Step-by-step explanation:  

Given, Coordinates of a triangle

$A\left ( -2,2 \right )$         $B\left ( 8,-2 \right )$          $C\left ( -4,-3 \right )$

Distance between two points is$=\sqrt{\left ( x_{1} -x_{2}\right )^{2}+\left ( y_{1}-y_{2} \right )^{2}}$

$AB=\sqrt{\left ( -2-8 \right )^{2}+\left ( 2+2 \right )^{2}}=\sqrt{10^{2}+4^{2}}$

$AB=\sqrt{116}$ units

$BC=\sqrt{\left ( 8+4 \right )^{2}+\left ( -2+3 \right )^{2}}=\sqrt{12^{2}+1^{2}}$

$BC=\sqrt{144+1}=\sqrt{145}$ units

$AC=\sqrt{\left ( -2+4 \right )^{2}+\left ( 2+3 \right )^{2}}=\sqrt{2^{2}+5^{2}}$

$AC=\sqrt{4+25}=\sqrt{29}$ units

$\left ( BC \right )^{2}=\left ( AB \right )^{2}+\left ( AC \right )^{2}$

$145 =116+29$

$145=145$

$LHS=RHS$

ABC is a Right angle triangle  and right angle at B

Also this triangle is scalene.
