Help please w/ line segments! Okay, so this is the prompt: Draw a line segment, and copy it to the right of the original segment. Explain your steps, and justify each step used. Bisect the original line segment from problem one. Draw an angle, and copy it to the right of the original angle. Explain your steps, and justify each step used. Bisect the original angle from problem three. All of this has already been done and I know for sure that it's correct, but I can't explain the steps. Could someone please give me some descriptions?

    ^ These are sketched versions of the drawings - I just need explained steps to go with them. I don't have a straight edge (used a ruler instead) nor a compass. @nincompoop @ganeshie8 @jim_thompson5910 @aaronq If one of you aren't busy I would appreciate the help very much!

    ok so you have 2 problems: a) bisecting a line segment and b) bisecting an angle I'm not sure why you drew line segment CD when it wasn't used at all. You bisected AB instead anyways, the idea of bisecting a segment is that you use a compass and straight edge. You place the non-pencil part of the compass at point A. Then you place the pencil part at point B. The arc marks you see (highlighted in the drawing below) are formed when you draw a partial circle |dw:1440549515493:dw| Note: the pencil part does not have to be at point B. It could be somewhere between the halfway point and point B

    the same applies for the other set of arcs as well. Just place the center of the circle at point B this time. Basically mirror everything the arcs intersect at two points. Call them X and Y the line segment XY that forms is the perpendicular bisector of AB

    hopefully this is making sense?

    bisecting an angle step 1) draw angle ABC |dw:1440549804988:dw|

    place the nonpencil end of the compass at point B extend the compass to some point between A and B. It doesn't matter where draw an arc and make sure the arc cuts through BC |dw:1440549875106:dw|

    the arc intersects at points D and E |dw:1440549895387:dw|

    next adjust the width of the compass to be as long as segment DE ie place the nonpencil end at D and stretch the compass to point E keep this width and draw arcs such that the circles are centered at point D and point E |dw:1440549997327:dw|

    my drawing is a bit off, but if you use an actual compass it should be far more accurate |dw:1440550041532:dw|
