  1. Classifying Triangles Geometry

  2. Two Ways to Classify Triangles • By Their Sides • By Their Angles Geometry

  3. Classifying Triangles By Their Sides • Scalene • Isosceles • Equilateral Geometry

  4. Scalene triangle: A triangle that has no congruent (equal) sides

  5. Isosceles triangle: A triangle with at least two congruent (equal) sides

  6. Equilateral triangle: A triangle with three congruent (equal) sides and three equal angles

  7. Classifying Triangles By Their Angles • Acute • Right • Obtuse • Equiangular Geometry

  8. Acute Triangles • Acute triangles have three acute angles Geometry

  9. Right triangle: Has only one right angle (90 degrees) This box indicates a right angle or a 90-degree angle.

  10. Obtuse Triangles • Obtuse triangles have one obtuse angle Geometry
