Across
- 1. The point where the three perpendicular bisectors of a triangle meet
- 4. The point that is exactly halfway between two other points
- 5. When a figure can be divided into two identical halves that are mirror images of each other.
- 6. The circle that is inscribed inside a polygon, touching all of its sides.
- 9. A line segment that connects two non-adjacent vertices of a polygon.
- 12. It's a geometric transformation that enlarges or reduces a shape while keeping its form, with a constant scale factor from a central point.
- 14. A triangle in which all three sides are equal in length, and all angles are 60°
- 15. A line that divides an angle into two equal parts
Down
- 1. A line segment joining two points on a circle.
- 2. A rule that states that in a right-angled triangle, the square of the hypotenuse (the longest side) equals the sum of the squares of the other two sides
- 3. Triangles that are identical in shape and size, with equal corresponding sides and angles
- 7. A closed shape with straight sides, such as a triangle, rectangle, or pentagon
- 8. A line that a curve approaches but never actually touches
- 10. A line that crosses two or more other lines at different points.
- 11. A four-sided shape where all sides have equal length. Its opposite angles are equal, and its diagonals bisect each other at right angles (90°).
- 13. The point where the three medians of a triangle meet
