Max is bisecting a segment. First, he places the compass on one endpoint and opens it to a width larger than half of the segment. Then, he swings an arc on either side of the segment. What is his next step? Draw a point that is not on the segment.
Keep the compass the same width, and place it on the other endpoint.
Draw a ray from one endpoint of the segment.
Keep the compass the same width, and place it on the arc intersection.

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
