A pair of adjacent angles are ∠SUR and ∠RUT. They are adjacent because they share a common vertex U, a common side UR, and their non-common sides SU and UT lie on opposite sides of the common side.
Let's follow the steps to determine a pair of adjacent angles and explain why they are adjacent:
1. Identify Adjacent Angles: Adjacent angles are two angles that have a common vertex and a common side, but do not overlap. From the figure, we can see that angle SUR shares a common vertex U and a common side UR with angle RUT. Therefore, angles SUR and RUT are adjacent.
2. Explain Why They Are Adjacent: Angles SUR and RUT are adjacent because they share a common vertex (U), a common side (UR), and their non-common sides (SU and UT) are on opposite sides of the common side.
