Answer/Step-by-step explanation:
✔️<1 can be named in two ways using letters, with the middle letter being the letter of the vertex of the angle. Thus is can be named as:
[tex] \angle ADB [/tex] or as [tex] \angle BDA [/tex]
✔️It is unclear to name <1 as <D because <2 can equally be named as <2 since both angles share a common point or vertex D.
