4. A point on a line segment that divides it into two equal parts.
6. One of the sides of a triangle.
7. A line segment that joins a vertex to the midpoint of the side that is opposite to that vertex.
10. a² + b² = c²
11. A ray that splits an angle into two equal angles.
14. y-y₁=m(x-x₁)
16. Perpendicular distance drawn from the vertex to the opposite side of the triangle.
18. A one-dimensional figure, which has length but no width, and is made of a set of points which is extended in opposite directions infinitely.
20. The congruency between two pairs of sides and one pair of angles.
21. y=mx+b
22. The change in y coordinate with respect to the change in x coordinate of that line.
24. The pairs of angles formed on the same side of the transversal and in the same relative position.
25. A line that connects the midpoints of two triangle sides.

1. Changing the size of an object without changing its shape.
2. A point which is at the same or equal distance from two given points.
3. Two or more points that lie on the same plane.
5. The point of intersection of all the three interior angle bisectors of the triangle.
8. A figure which is formed by two rays or lines that shares a common endpoint.
9. A flat surface or area that extends infinitely in two dimensions and has no thickness.
12. The ratio of corresponding sides on two similar figures.
13. A two-dimensional surface formed by an x-axis and a y-axis.
15. A pair of adjacent, supplementary angles.
17. The longest side of a right-angled triangle compared to the length of the base and perpendicular.
19. Either of a pair of angles that have the same vertex and are on opposite sides of two intersecting straight lines.
23. All three sides of a triangle are congruent to the corresponding sides of another triangle, then the triangles themselves are also congruent.
