Across
- 1. A rectangle with all four sides of equal length.
- 2. The trig function cosine, which is written cos θ. For acute angles, cos θ can be found by the SOHCAHTOA definition
- 3. A closed plane figure for which all sides are line segments.
- 8. A line that touches a curve at a point without crossing over.
- 10. A unit for measuring angles. 180° = π radians, and 360° = 2π radians.
- 12. A point at which a graph intersects the x-axis.
- 14. Half a circle. That is, a 180° arc.
- 17. A box shape on a plane.
- 18. Two distinct coplanar lines that do not intersect.
- 19. side-angle-side
- 21. A transformation in which a figure grows larger.
- 24. Like a line
- 26. A nonnegative number that must be multiplied times itself to equal a given number.
- 28. Another word for average.
- 29. The longer of the two arcs between two points on a circle.
- 30. side-side-angle
Down
- 1. A line which passes through at least two points of a curve.
- 4. A polygon with three sides
- 5. A point at which a graph intersects the y-axis.
- 6. A line segment between two points on the circle or sphere which passes through the center.
- 7. A part of a line starting at a particular point and extending infinitely in one direction.
- 9. A line that cuts across a set of lines or the sides of a plane figure.
- 11. An expression used to calculate a desired result, such as a formula to find volume or a formula to count combinations.
- 13. A polygon with four sides.
- 15. The study of geometric figures in two dimensions (plane geometry) and three dimensions (solid geometry)
- 16. The distance around the outside of a plane figure.
- 20. A way of remembering how to compute the sine, cosine, and tangent of an angle.
- 22. The locus of all points that are a fixed distance from a given point.
- 23. A corner point of a geometric figure.
- 25. side-side-side
- 27. The symbol, which is used to indicate square roots or nth roots.
