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: B+E = 180</h3>
Angles B and D are corresponding angles. This means D = B since corresponding angles are congruent when we have parallel lines.
Then note how D+E = 180 as these two angles form a straight angle.
Replace D with B getting B+E = 180 (this is the substitution property).
Alternatively, you can say that G = E and B+G = 180 to lead to B+E = 180. There are many other routes to take as well.
