π Figure adjustment involves adjusting the triangle so that the summation of its angles is 180 degrees.
π’ We can use the angles adjusted in the station adjustment to perform figure adjustment.
π By calculating the angles of triangle BHG (47Β°59'38''), HGF (66Β°50'29''), and FGB (65Β°6'21''), the summation is 179 degrees.
π The error in the chain of triangles adjustment is calculated by subtracting the measured angle from 180 degrees.
π To correct the error, divide it by three and add the result to the measured angles.
π’ After the adjustment, the angle B becomes 48 degrees, 0 minutes, and 48.667 seconds.
π The video discusses the adjustment of a triangle using figure adjustment.
π The angles h and f of the triangle are adjusted to 66 degrees 51 minutes 39.667 seconds and 65 degrees 7 minutes and 31.667 seconds, respectively.
π Another example is demonstrated with the adjustment of triangle iem or triangle ime where angle i is set to 52 degrees.
π’ The video discusses how to calculate the error and correction in a chain of triangles adjustment.
βοΈ By summing up the angles, one can determine the total degree of error.
π To find the correction, the error is divided by three.
π The video discusses how to adjust the angles in a chain of triangles.
π By adding a correction value to each angle, the angles can be adjusted accordingly.
π The final step is to tabulate the adjusted angles in a table.
π Figure adjustment is a method used to modify angles in a chain of triangles.
π Figure adjustment follows the station adjustment in modifying angles.
π‘ Figure adjustment is an important technique in surveying and geometry.
