A student measured ∠XYZ angle x y zand said that m∠XYZ= 120°. m angle x y z equals 120 degreesExplain the student's error.

Question

An acute angle has three plotted points, X, Y, and Z.

Answer 1

The student's error is that they only measured two points, X and Y, and assumed that the angle was 120°. The student should have measured all three points to accurately determine the measure of the angle.
