Triangle Figure Adjustment: Achieving Accurate Measurements

🔍 Figure adjustment involves adjusting the triangle so that the summation of its angles is 180 degrees.

🔢 We can use the angles adjusted in the station adjustment to perform figure adjustment.

📐 By calculating the angles of triangle BHG (47°59'38''), HGF (66°50'29''), and FGB (65°6'21''), the summation is 179 degrees.

🔑 The error in the chain of triangles adjustment is calculated by subtracting the measured angle from 180 degrees.

📏 To correct the error, divide it by three and add the result to the measured angles.

🔢 After the adjustment, the angle B becomes 48 degrees, 0 minutes, and 48.667 seconds.

🔑 The video discusses the adjustment of a triangle using figure adjustment.

🔑 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.

🔑 Another example is demonstrated with the adjustment of triangle iem or triangle ime where angle i is set to 52 degrees.

🔢 The video discusses how to calculate the error and correction in a chain of triangles adjustment.

⚖️ By summing up the angles, one can determine the total degree of error.

🔄 To find the correction, the error is divided by three.

📐 The video discusses how to adjust the angles in a chain of triangles.

📏 By adding a correction value to each angle, the angles can be adjusted accordingly.

📊 The final step is to tabulate the adjusted angles in a table.

📐 Figure adjustment is a method used to modify angles in a chain of triangles.

🔄 Figure adjustment follows the station adjustment in modifying angles.

💡 Figure adjustment is an important technique in surveying and geometry.
