4. Help your students learn to about complementary, supplementary, and vertical Angles with these printable teaching resources

5. An Altazimuth differs from a theodolite in the higher precision with which angles, especially vertical angles, are measured

6. The horizontal angles ( (beta) correspond to the longitude and the vertical angles ( (alpha) to the latitude (see Annex 3).

7. With two mirrors, the scanner calculates the beam's horizontal and vertical angles, giving accurate x, y, and z coordinates.

8. In the above figure, 1 and 3, 2 and 4, 6 and 8 and 5 and 7 are vertical Angles.

9. Angles which have a common vertex and the sides of the angle are formed by the same lines are known as vertical Angles

10. ESC Bollards can cope with horizontal angles of ± 90° (except for pillar Bollards which is in all horizontal angles) and vertical angles up to 60° depending on bollard type
