Are angle one and angle two
adjacent angles?
We say that angles are adjacent if
they share a common vertex and a common side. The vertex is of course the
endpoint of the rays that form the sides of the angle. Angle one is this one, and let’s
highlight angle two in yellow. So do these two angles have a
common vertex and a common side? Well, they have a vertex here
that’s shared; it’s a common vertex. And in fact they have a common side
here, so they share a vertex and a side, meaning yes, angle one and angle two are
adjacent.
