  1. 1. Types of Triangle and Angles of Triangles Classification and Properties
  2. 2. Types of Triangles <ul><li>Classification by Angles: </li></ul><ul><li> Right Triangle- the largest angle in the triangle is EXACTLY 90  </li></ul><ul><li>Acute Triangle- the largest angle in the triangle is less than 90  </li></ul><ul><li>Obtuse triangle- </li></ul><ul><li>the largest angle in the triangle </li></ul><ul><li>is greater than 90  </li></ul><ul><li>Equiangular Triangle- </li></ul><ul><li>All three angles are congruent </li></ul>
