Question

carlos colon... share a vertex and a side be supplementary be complementary be congruent none of these adjacent angles must 12/40

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles are two angles that share a common vertex and a common side.

Step2: Analyze each option

• "Be supplementary": Adjacent angles do not have to be supplementary. For example, two adjacent angles of \(30^{\circ}\) and \(40^{\circ}\) are not supplementary.
• "Be complementary": Adjacent angles do not have to be complementary. For example, two adjacent angles of \(50^{\circ}\) and \(60^{\circ}\) are not complementary.
• "Be congruent": Adjacent angles do not have to be congruent. For example, two adjacent angles of \(20^{\circ}\) and \(30^{\circ}\) are not congruent.

Answer:

None of these
