In order to find the lenght of the triangles you may use the next formula
<span>A(x1 , y1) , B(x2 , y2) </span>
<span>AB = sqrt[(x1-x2)^2+(y1-y2)^2]
</span>Still I have to say that the triangle you are describing is definitely Isosceles
I hope this works for you
Answer:
D. 8
Step-by-step explanation:
See the picture for steps
obtuse angles are having value greater than 90 degree.
