Question 181611
<font face="Times New Roman" size="+2">


Two congruent sides means that the triangle is isoceles and therefore also has two congruent angles.  So, for your larger triangle, you must have a 30 degree angle and two 75 degree angles because the sum of the interior angles must be 180.  (two 30 degree angles and a 120 degree angle is impossible because you said the longer sides are congruent).  For the smaller triangle, you must have two 70 degree angles and a 40 degree angle (again two 40s and a 70 not possible because the longer sides are congruent).  The angle measures in the two triangles are <i><b>not</b></i> equal, therefore the triangles are <i><b>not</b></i> similar.
