Answer 2

Any angle can be named by a single letter, If the letter represents its vertex.

In the given angle RST,

S is the vertex.

1 is the name given to angle.

So we can name the angle in the following ways

<RST, <TSR, <1, <S.

Here R is a point on one of the arms of the angle and is not a vertex.

Hence we cannot name the angle as <R.

All of the following are acceptable ways to name the angle shown except <R.
