Question 322771
<font face="Garamond" size="+2">


Triangle TRY is isosceles by the definition of isosceles -- at least two of the sides of the triangle have the same measure.  But not having the diagram or any other information, I can't tell you what would lead you to think that TY and TR are either congruent or equal in measure.
