Question

if an angle can be divided in half by constructing a bisector, then what method doubles an angle? (1 point)
constructing a copy of the bisected angle attached to the original angle
bisecting the angle twice
constructing a copy attached to the original angle
constructing two of the bisected angles

Explanation:

To double an angle, we can construct a copy of the angle and attach it to the original angle. Bisecting an angle reduces its measure, so bisecting twice is incorrect. Constructing two of the bisected - angles is equivalent to the original angle if we started with the bisection process. Constructing a copy of the bisected angle attached to the original angle is also incorrect as it doesn't double the original non - bisected angle.

Answer:

constructing a copy attached to the original angle
