Correct Answer: A
Explanation:
To construct two 45° angles from a 90° angle a bisection must occur. Recall that bisection means to cut an angle into two equal parts.
Since
90°/2=45°
that makes a bisection of the 90° angle equal two 45° angles and thus is the solution.
Moving the terminal ray will not create two angles and thus it cannot be the solution.
Nonterminal is not the correct terminology and therefore, it cannot be the correct solution.
