What is the first step in constructing the angle bisector?

​ ​ (a)  

• Draw an arc that intersects both sides of angle
• Draw ray from the vertex through the intersection
• Draw a line segment connecting points 𝐵 and 𝐶.
• Draw arcs from B & C that intersect

• Adjust the compass width to be more than half of the length of the line segment. Then, draw an arc above and below line segment AB.

• Using a straightedge, draw a line connecting the points where the arcs intersect.

• Without changing the size of the compass opening, center the compass on point B and draw an arc above and below line segment AB so that these arcs intersect the other two arcs drawn.

Listed below, not in order, are the steps for copying ∠A using a compass and a straightedge.  Place the steps in the correct order. If necessary, watch the video!

• Draw a ray from the vertex through the intersection of the arcs.

• Place the compass on the vertex of the original angle and draw an arc that intersects both legs.

• Set the compass to the distance between the intersections of the first arc with the legs of the angle. Use this setting to draw a third arc centered where the second arc intersects the reference ray.

• Draw a reference ray.

• Without changing the setting, place the compass on the starting point of the ray and draw an arc intersecting the ray.
