Across
- 3. a2 + b2 = c2.
- 4. the point where the three angle bisectors meet. This point is the same distance from each of the three sides of the triangle.
- 5. point where the three altitudes meet, making them concurrent.
- 7. point where the three perpendicular bisectors meet.
- 9. point where the three medians meet. This point is the center of mass for the triangle
- 11. specifies only location; it has no length, width, or depth.
Down
- 1. line segment connecting a vertex to the line containing the opposite side and perpendicular to that side.
- 2. point where two sides of a polygon meet.
- 3. goes through the midpoint of the segment, creating two equal segments.
- 6. triangle with all three sides unequal.
- 8. any polygon with an angle measuring more than 180°.
- 10. has a point on one end, and it extends infinitely in the other direction.
