  10. Review A polygon is a simple, closed, figure made up of line segments. A polygon is classified by the number of sides it has.

  11. Can you classify these polygons?

  12. Regular Polygons • A regular polygon has all sides and all angles congruent. B A Which is a regular polygon?

  13. Triangles • Triangles can be classified by their sides or by their angles.

  14. Triangles Classifying triangles by the angles….

  15. Acute TriangleAll angles are acute.

  16. Right TriangleContains one right angle.

  17. Obtuse TriangleContains one obtuse angle.

  18. Classify Triangles by their angles • Acute • All angles are acute • Right • Contains one right angle • Obtuse • Contains one obtuse angle

  19. TRIANGLES Classifying triangles by their sides…

  20. TRIANGLES SCALENE
