When comparing measures of angles and segments, what symbol is used?

When comparing measures of angles and segments, the symbol used is indeed the equals sign (=). This symbol indicates that two quantities are exactly the same in value.

In the context of geometry, when stating that two angles or segments have the same measure, it is appropriate to use the equals sign to denote that their numerical values are equal. For example, if angle A measures 30 degrees and angle B measures 30 degrees, one can express this relationship by writing ∠A = ∠B, meaning they are equal in measure.

Other symbols serve different purposes: for instance, the symbol for approximate equality (≈) is used when values are close but not exactly the same, the congruence symbol (≅) indicates that two figures are congruent in shape and size, and the similarity symbol (∼) signifies that figures are similar but not necessarily the same size. Therefore, the use of the equals sign is specific to cases where two measures are identically the same.
