Across
- 3. A term meaning completely equal or the same distance away from two or more specific points or lines.
- 5. The point where all three perpendicular bisectors of a triangle cross each other. It is the center of the circle that passes through all three outer corners of the triangle.
- 7. The point where all three medians of a triangle cross each other. It acts as the balancing center of gravity for the triangle.
- 9. Bisector A line or ray that cuts an angle exactly in half to create two smaller, perfectly equal angles.
- 10. The point where all three altitudes (height lines) of a triangle cross each other.
- 12. A segment that connects the midpoints of two sides of a triangle. It is always parallel to the third side and exactly half its length.
Down
- 1. Bisector A line, ray, or segment that cuts a side of a triangle exactly in half at a perfect 90-degree angle. It does not have to start at a corner vertex.
- 2. Triangle A triangle that contains exactly one perfect 90-degree angle.
- 4. A perpendicular segment drawn from a corner (vertex) of a triangle to the opposite side, meeting it at a perfect 90-degree angle. This represents the true height of the triangle.
- 6. Triangle A triangle where all three individual interior angles are small (less than 90 degrees).
- 8. The point where all three angle bisectors of a triangle cross each other. It is the center of the circle that fits perfectly inside the triangle.
- 10. Triangle A triangle that contains exactly one large interior angle that is greater than 90 degrees.
- 11. A line segment drawn from any corner (vertex) of a triangle to the exact middle point (midpoint) of the opposite side.
- 12. The exact middle point of a line segment that divides it into two perfectly equal parts.
