GEOMETRY

4. The common endpoint of two or more rays or line segments
6. is a true statement, which does not require to be proved.
8. is a line segment from a vertex of the triangle to the midpoint of the side opposite that vertex
11. point of concurrency of an altitude
13. point of concurrency of angle bisector
14. are coplanar lines that does not intersect
18. a side of an angle
19. angle measures more than 90 degrees
25. is the longest side of a right-angled triangle, the side opposite of the right angle
26. is the perpendicular segment from a vertex to its opposite side
28. angle measures exactly 90 degrees
30. point of concurrency of perpendicular bisector

1. The portion of a line between any two points on the line
2. The side of a triangle which is perpendicular to the altitude.
3. is the part of a conditional statement just after the word if.
5. 2 coplanar line with a common side
7. formed by two intersecting lines
9. points that lie on the same line
10. precise location or place on a plane. Usually represented by a dot.
12. a set of properly ordered and accurately justified conditional statements
15. a ray that divides the angle into 2 congruent angles
16. a line with two endpoints
17. formed by 2 non-collinear rays with a common endpoint
20. A proposition that has been or is to be proved on the basis of explicit assumptions.
21. angle measure less than 90 degrees
22. A geometrical object that is straight, infinitely long and infinitely thin.
23. are lines that are not coplanar
24. is the "then" part of a conditional statement.
27. point of concurrency of median
29. either of the sides in a right triangle opposite an acute angle.are the two shorter sides of the triangle
