  1. 5-3 altitude of a triangle , orthocenter , concurrency of altitudes of a triangle theorem Anna Chang T2

  2. Altitude of a triangle • Perpendicular line from a vertex to the the opposite side • All the triangle have three altitudes • Can be inside, outside, on the triangle The red lines are the altitudes

  3. eXAMPLES

  4. oRTHOCENTER • Point where all of the altitudes meet. • acute triangle is inside the triangle. right triangle is on the vertex of the 90 degrees angle. obtuse triangle is on the outside of the triangle. The yellow point is the orthocenter

  5. examples

  6. concurrency of altitudes of a triangle theorem • three altitudes of any triangle are concurrent. (this point of concurrency is called orthocenter)
