Classifying Triangles You can classify triangles by their angle measures. An equiangular triangle, for example, is a triangle with three congruent angles. Examples of three other . Classifying Triangles and Quadrilaterals Date_____ Period____ Classify each triangle by its angles and sides. 1) equilateral 2) obtuse isosceles 3) obtuse scalene 4) acute isosceles 5) . For each triangle, mark the box that matches its type when classifying by sides. The marks on the sides of the triangles show when two sides are “congruent” or the same length.
