Final answer:
The correct answer is A) SharedVertexAngles(). Adjacent angles are two angles that have the same vertex and a common side between them. The sum of the measures of adjacent angles around a vertex is always 360 degrees.
Step-by-step explanation:
The correct answer is A) SharedVertexAngles().
Angles that share a vertex are called adjacent angles. In geometry, adjacent angles are two angles that have the same vertex and a common side between them. They do not overlap. The sum of the measures of adjacent angles around a vertex is always 360 degrees.
For example, if angle A is 30 degrees and angle B is 60 degrees, the measure of angle C would be 360 - 30 - 60 = 270 degrees.
