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

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
