PPT-Horizontal Angle Measurement

Theodolites or Transits can Measure horizontal angles vertical angles distances stadia elevations Components of a Theodolite Vertical axis Horizontal axis Line of sight Vertical circle. Measur i ng Instruments Tacheometers And Theodolites Angle s & Directions An angle is defined as the difference in direction between two convergent lines . A horizontal angle is formed by the direc Angle:. In Geometry an . angle. is the figure formed by two rays sharing a common end point, called the vertex of the angle.. . The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other.

If you throw a ball down the hall, what is the path the ball travels? What shape does it make? What affects the motion of the ball?. Objects fired at an upward angle have a horizontal and a vertical component of motion . that can be found using the trig functions of sine, cosine, and tangent..

Find the component form of the vector that represents the velocity of an airplane descending at a speed of 150 mph at an angle of 30. -Quiz Friday over Pythagorean Theorem/Special Right Triangles/Trig Ratios.. Theodolite/diopter . Inclinometer / Clinometer. Sextant – used to measure the angle between two known objects, usually using a celestial object such as the sun or Polaris (north star). The major use is to identify lines of latitude and sighting the height of a landmark to determine distance off from the landmark. Forces applied at an angle. When forces are applied at angles other than 90. o. ,. we need to resolve the force into its component vectors. . Then, we . find the net force in each direction, . write our force equations (. o.
