Across
- 4. A straight line which links two points without extending beyond them.
- 5. a geometric shape that is a combination of lines, points, or planes that form a closed boundary.
- 6. a ratio with a relationship between the dimensions and the corresponding dimensions on the actual figure.
- 8. a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
- 10. lines that lie in the same plane, and are the same distance apart over their entire length.
- 11. A point on a line segment that divides it into two equal parts.
- 12. a mathematical statement that two ratios are equal to each other.
Down
- 1. divides the angle into two angles with equal measures.
- 2. have the same shape, or if one has the same shape as the mirror image of the other.
- 3. a line that intersects a given line segment at a 90-degree angle (perpendicular) and also passes through the midpoint of that line segment, effectively dividing it into two equal parts.
- 7. identical in shape and size.
- 9. a line segment through a given vertex (called apex) and perpendicular to a line containing the side or edge opposite the apex.
