Best ResponseYou've already chosen the best response.2dw:1438221440750:dw

Best ResponseYou've already chosen the best response.2line t is a perpendicular bisector of segment AB "bisect" means to cut in half, so AB is cut in half. Into two congruent pieces dw:1438221542735:dw

Best ResponseYou've already chosen the best response.2"perpendicular" means we have a 90 degree angle dw:1438221568512:dw and all right angles are congruent

Best ResponseYou've already chosen the best response.2dw:1438221591388:dw what can you tell me about triangle ADC and triangle BDC ?

Best ResponseYou've already chosen the best response.2well my drawing is a bit off, so don't base everything on that

Best ResponseYou've already chosen the best response.2is segment AD congruent to segment DB ?

jim_thompson5910

Best ResponseYou've already chosen the best response.2how about angle ADC and angle BDC are they congruent?

jim_thompson5910

Best ResponseYou've already chosen the best response.2both are 90 degrees, yes

jim_thompson5910

Best ResponseYou've already chosen the best response.2and certainly DC is congruent to itself, ie DC = DC (reflexive property)

jim_thompson5910

Best ResponseYou've already chosen the best response.2so we can use the SAS property of congruence to say that triangle ADC = triangle BDC

Best ResponseYou've already chosen the best response.2finally using CPCTC http://www.mathwarehouse.com/geometry/congruent_triangles/congruentpartsCPCTC.php we can show that AC = BC dw:1438221961389:dw

Best ResponseYou've already chosen the best response.2all of this is basically saying "C is the same distance away from either A or B"

Best ResponseYou've already chosen the best response.2what do you have so far for the paragraph

jim_thompson5910

Best ResponseYou've already chosen the best response.2does my explanation make sense?

jim_thompson5910

Best ResponseYou've already chosen the best response.2so try to write a paragraph based on what was explained above. Write out a rough draft and I'll help you work on the paragraph

Best ResponseYou've already chosen the best response.2show me what you have so far

Best ResponseYou've already chosen the best response.2what information is given in the problem

jim_thompson5910

Best ResponseYou've already chosen the best response.2yes I see that, but I want to have you write it out in words

jim_thompson5910

Best ResponseYou've already chosen the best response.2that's usually where proofs start from: the information given

jim_thompson5910

Best ResponseYou've already chosen the best response.2"angle 4 is congruent to angle 6" we don't know that yet as it's not given

jim_thompson5910

Best ResponseYou've already chosen the best response.2"line t is a perpendicular bisector" to what?

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2other than line t, what other segment is shown?

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2so the given information is "line t is a perpendicular bisector of segment AB"

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2That's where I would start the proof

jim_thompson5910

Best ResponseYou've already chosen the best response.2Then we can move onto the next piece you stated: "angle 4 is congruent to angle 6" how do we know that "angle 4 is congruent to angle 6" ?

jim_thompson5910

Best ResponseYou've already chosen the best response.2they actually are. Scroll up to remember why

jim_thompson5910

Best ResponseYou've already chosen the best response.2why is angle 4 congruent to angle 6 ?

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2which is what?

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2no, 90 degrees

jim_thompson5910

Best ResponseYou've already chosen the best response.2perpendicular > 90 degrees

jim_thompson5910

Best ResponseYou've already chosen the best response.2perpendicular > right angle > 90 degrees

jim_thompson5910

Best ResponseYou've already chosen the best response.2line t is a perpendicular bisector of segment AB angle 6 = angle 4 because we have 2 right angles. All right angles are congruent since they are 90 degrees

Best ResponseYou've already chosen the best response.2basically I'm going through the proof I wrote out above. The key is writing it in your own words as if you're explaining it to a teacher, friend, etc.

jim_thompson5910

Best ResponseYou've already chosen the best response.2yeah it should all be here. Try giving it a shot in terms of writing it

jim_thompson5910

Best ResponseYou've already chosen the best response.2yeah so far so good. Try to rewrite in terms of how you would say it
