Does the diagram show an adjacent angle?
Yes
If one of two corresponding angles is a right angle, then the other angle will also be a right angle.
Two angles are adjacent when they share a common vertex and a common side, but have no interior points in common. Think of them as neighbors that touch but don't overlap!
No! Adjacent angles must share a common side, which means they need to be formed by rays that meet at the same point. Different lines create separate angle pairs.
Vertical angles are opposite each other when two lines intersect, while adjacent angles are next to each other. Vertical angles are equal, but adjacent angles just need to share a side.
Not always! Adjacent angles only add to 180° if they form a linear pair (a straight line). Regular adjacent angles can add up to any amount.
Look for angles that share a vertex (the point where lines meet) and share exactly one side (ray or line segment). They should touch but not overlap.
