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

• 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.

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

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!

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

• Draw a reference ray.

• 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.

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

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