help

OpenStudy (studygurl14):

Hello. What's your question?

OpenStudy (studygurl14):

We can't do your entire homework for you. What are you having trouble with?

OpenStudy (anonymous):

WITH THE POWER OF LOVE YOU WILL FIND THE SOLUTION TO EVERY DOUBT IN YOUR MIND

OpenStudy (anonymous):

well what do you need help with?

OpenStudy (danjs):

close the thread

OpenStudy (danjs):

yeah , close the question to get it off the main page

OpenStudy (danjs):

ok, name a number and ill help , same kind of stuff as yesterday

OpenStudy (anonymous):

YOU CAN FIND YOUR WAY WITH THE POWER OF LOVE.

OpenStudy (danjs):

The congruence theorems are pg2 #17 - 20, that you can use to prove congruent

OpenStudy (danjs):

For a) the two triangles share that side AC so that is equal to itself, and all three sides are the same, side-side side-SSS

OpenStudy (danjs):

b) same reason, SSS, DC = AB from rectangle property, AD=BC as marked, and the diagonal equals itself... side-side-side

OpenStudy (danjs):

you just need to look for one of those orders, ASA, SSS, SAS, AAS

OpenStudy (danjs):

c) you can use a number of them, SSS, SAS, ASA, AAS, any really, since it is a rectangle you can show te angles and sides are equal

OpenStudy (danjs):

rectangles have equal opposite sides that are parallel, the angles are 90 at the corners, you can show these things from being a rectangle

OpenStudy (danjs):

all 3 corresponding sides are the same, and all 3 angles the same for both

OpenStudy (danjs):

for d) EB and BC are equal corresponding sides, (rotate one trignale 180 to line up the right sides) , angle C and E are marked the same corresponding angles, and you can also say, the angles at B are equal vertical angles, thus you have ASA

OpenStudy (danjs):

yes that could be shown

OpenStudy (danjs):

|dw:1453427310380:dw|

OpenStudy (danjs):

the quick thing to see here is that this has two equal sides, isocelese, and the angles across from equal sides are also equal.... |dw:1453427373608:dw|

OpenStudy (danjs):

then, just remember the angles for a triangle total 180 degrees x + x + 68 = 180

OpenStudy (danjs):

2x = 180-68 = 112 x = 56

OpenStudy (danjs):

so for 32) same idea, except they gave you equal angles, the sides across them are equal the same as the last triangle was

OpenStudy (danjs):

3x - 5 = x + 11 2x = 16 x=8

OpenStudy (danjs):

Where to now?

OpenStudy (danjs):

34 - 37 are just like ones from yesterday, you can re-read those on there

OpenStudy (danjs):

just remember 2 sides have to be greater than the third side for any sides of a triangle

OpenStudy (anonymous):

okay

OpenStudy (danjs):

You good with the proof things like 30)

OpenStudy (anonymous):

my pc died

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

the proofs not very good at it

OpenStudy (danjs):

ill do that one real quick... those things include a bunch of the concepts from many other probs, so if you can do this , should be able to do most others

OpenStudy (anonymous):

okay

OpenStudy (danjs):

|dw:1453428133728:dw|

OpenStudy (danjs):

For the most part, you start with somethign Given and go from there... so the first line... AT = GS; AT || GS -------> Givens
