One of the base angles of an isosceles triangle has a measure of 65. What is the measure of the vertex angle?
\n" ); document.write( "-----------------
\n" ); document.write( "The 2 base angles are equal, so the other is also 65º. They add to 130º. The sum of the angles of all triangles is 180, so the vertex angle is 50º.
