9. a line segment drawn from the vertex of the triangle to the opposite side, forming a perpendicular angle with that side
12. point where three or more lines or rays intersect with each other
13. corresponding sides maintain a constant ratio
14. the point where all three medians of a triangle intersect

1. figures that have the same ratio of corresponding sides and equal pair of corresponding angles
2. a line perpendicular to a side of a triangle and passing through its midpoint
5. a straight line that divides the angle into two congruent angles
7. a set of lines that all intersect at a single point of a triangle
8. a point where the perpendicular bisectors of the three sides of a triangle intersect
