                   Medians, Altitudes and Angle Bisectors

Part One. Draw each of the following. Make sure all parts are labeled and marked
appropriately.

1. PS is a median of PQR and                           2. QT is an angle bisector of PQR
S is between Q and R                                    and T is between P and R




3. AC and BC are both altitudes of ABC                 4. PT and RS are medians of PQR
                                                        and intersect at point V




Part Two. Tell if each of the following statements are ALWAYS, NEVER, or
SOMETIMERS true.

5. The three medians of a triangle intersect at a point inside the triangle.

6. The three angle bisectors of a triangle intersect at a point outside the triangle.

7. The three altitudes of a triangle intersect at a vertex of the triangle.

8. If a median of a triangle is also an altitude, then the triangle is isosceles

9. A point on the angle bisector of a triangle is equal distances from the sides of the
triangle.
