Used in geometry, the isosceles triangle can be classified as acute, right or obtuse, depending on the vertex angle. An acute isosceles triangle has a vertex angle of less than 90 degrees. A right isosceles triangle has a vertex angle of exactly 90 degrees. An obtuse isosceles triangle has a vertex angle of more than 90 degrees.
