Across
- 3. The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet
- 4. The point at which the sides of an angle intersect
- 5. Angles who share the same initial side and terminal sides
- 7. Either of two angles whose sum is 90°
- 9. Are triangles whose corresponding angles are the same, but whose corresponding sides may be of different lengths
- 12. A sixtieth of a minute of angular distance
- 13. An angle of 90°
- 14. An angle less than 90°
- 15. A stationary straight line that contains a point about which another straight line is rotated to form an angle
- 17. Either of two angles whose sum is 180°
- 20. The initial side is on the positive x-axis, while the other side or terminal side is defined by the measure from the initial side in radians, degrees, or turns
Down
- 1. An angle in standard position whose terminal ray lies along one of the axes
- 2. The position of an angle with its vertex at the origin of a rectangular-coordinate system and its initial side coinciding with the positive x-axis
- 5. Triangles with corresponding sides and angles that are congruent, giving them the same size and shape
- 6. Initial Side of an Angle is defined as the ray where measurement of an angle starts
- 8. An angle that measures more than 90 degrees but less than 180 degrees
- 9. An angle of 180°
- 10. A sixtieth of a degree of angular measurement
- 11. An angle is in standard position if its vertex is located at the origin and one ray is on the positive x-axis
- 16. Each of the pairs of opposite angles made by two intersecting lines
- 18. Negative angles are a way of measuring an angle from a different direction
- 19. A unit of measurement of angles, one three-hundred-and-sixtieth of the circumference of a circle
