NAME _____________________________________________ DATE ____________________________ PERIOD _____________ 4-1 Guided Notes Classifying Triangles Classify Triangles by Angles One way to classify a triangle is by the measures of its angles. Classify Triangles by Sides You can classify a triangle by the number of congruent sides. Equal numbers of hash marks indicate congruent sides. Exercises Classify each triangle as acute, equiangular, obtuse, or right. 1. 2. 3. 4. 5. 6.

ALGEBRA Find x and the length of each side if △RST is an equilateral triangle. Classify 8. ALGEBRA Find y and the length of each side if △ABC is isosceles with AB = BC. PQO by its sides. Classify ΔABC by its sides. Then determine if the triangle is a right triangle. The vertices are A(0,0), B(3,3) and C(-3,3). Chapter 4 6 Glencoe Geometry
