"Find vertical angles, two parallel lines with a transversal that intersects them, or a perpendicular bisector in your everyday world. Take a picture of it. Then, create a given and prove statement for the figure. Finally, write a proof using at least one of the following theorems: -Vertical Angles - Corresponding Angles - Alternate Interior Angles - Equidistance of a Point on a Perpendicular Bisector" I have a picture i just don't understand what to write.. I'll post my picture.. I was doing the Vertical Angles one.
ok so let me dumb down the picture for math usage :)|dw:1421009705464:dw|
how do i prove it?
well, there isn't anything to prove
you need to say something first, so you chose vertical angles, what does that theorem say?
Vertical angles are always congruent
ok, so you need to be given some angle you can apply that to, so, literally pick an angle
i guess angle D and angle C
well, only pick one for now
but yea, those are a pair, so you are given the measure of angle D, what is the measure of angle C?
Well for the sign the angles are all 90*
more simple than that
you don't need any actual measurements
all the angles are the same?
well, you don't know that for a fact
so if you are only given angle D, what other angle do you know the measure of?
C
right, and how do you know that?
