Question 156453
GE = y, EH = y-1, GH = 11


If this is a triangle: any two sides added together must exceed the measure of the third side (that's a property of triangles).


So:
{{{(GE + EH) > GH}}}
{{{(y+y-1)>11}}}
{{{(2y-1)>11}}}
{{{(2y)>12}}}
{{{y>6}}}


If this is a line segment: the parts add up to the whole.


So:
{{{(GE + EH)=GH}}}
{{{(y+y-1)=11}}}
{{{(2y-1)=11}}}
{{{(2y)=12}}}
{{{y=6}}}


I hope this helped!
