To bisect angle \( \angle ABC \) using a reflective device like a Mira, the correct approach is:
D. Place one end of the reflective device on the vertex B and swing the other end until you can see the reflected line segment BC coincide with line segment AB.
This method ensures that you are correctly positioning the reflective device to find the bisector of the angle at vertex B, where the lines AB and BC meet.
When using a reflective device such as a Mira to bisect angle ABC, where should the reflective device be placed?
A. Place the reflective device along line segment AC.
B. Place one end of the reflective device on the vertex A and swing the other end until you can see the reflected line segment AB
coincide with line segment AC.
C. Place the reflective device along line segment AB.
D. Place one end of the reflective device on the vertex B and swing the other end until you can see the reflected line segment BC
coincide with line segment AB.
