Any point that is on the perpendicular bisector of asegment is equidistant from the endpoints of thatsegment.A2. The circumcenter of a triangle is equidistant from themidpoints of each side of the triangle. D3. The altitudes of a triangle meet at the orthocenter. A4. Three altitudes can be drawn for any one triangle. A5. A median of a triangle is any segment that contains themidpoint of a side of the triangle. D6. The measure of an exterior angle of a triangle is alwaysgreater than the measures of either of its correspondingremote interior angles.A7. The longest side in a triangle is opposite the smallestangle in that triangle. D8. To write an indirect proof that two lines areperpendicular, begin by assuming the two lines are notperpendicular.A9. The length of the longest side of a triangle is alwaysgreater than the sum of the lengths of the other twosides.D10. In two triangles, if two pairs of sides are congruent,then the measure of the included angles determineswhich triangle has the longer third side.A
