Help with Geometry Question

OpenStudy (dan815):

yes?

OpenStudy (abbie):

OpenStudy (dan815):

okay we should get rid of the easy to spot congruent ones first

OpenStudy (dan815):

the 2 middle triagles boe and coe are congruent

OpenStudy (anonymous):

3pairs? AOE and DOE COE and BOE ABO and DCO

OpenStudy (dan815):

no there are more

OpenStudy (dan815):

but go one at a time proove each one to be true

OpenStudy (dan815):

there are around 5 or 6 pair i think

OpenStudy (anonymous):

Nah...

OpenStudy (dan815):

yes

OpenStudy (anonymous):

Give me more...

OpenStudy (dan815):

boe=coe AOE=COE ABE=DCE OAB=ODC OBE= OCE <--wih the back connection on the tiny middle triangles

OpenStudy (dan815):

nvm the last one is not tangle to that one i think

OpenStudy (dan815):

woh wait they are

OpenStudy (dan815):

i have feeling there a 6 and 7ths one somewhere

OpenStudy (anonymous):

Aoe And. Coe are not congruent

OpenStudy (anonymous):

Look carefully

OpenStudy (dan815):

AOE and DOE sry

OpenStudy (anonymous):

Hmmm...there are four...not more than that

OpenStudy (dan815):

therse more

OpenStudy (dan815):

if i had a mouse itd be easier to show, but let her prove those first xD

OpenStudy (anonymous):

Lol

OpenStudy (abbie):

how do you prove them?

OpenStudy (anonymous):

All of them are congruent by SSS rule

OpenStudy (abbie):

so what is the answer?

OpenStudy (anonymous):

AOE and DOE COE and BOE ABO and DCO ABE and DCE 4 pairs

OpenStudy (abbie):

and what is the proof that they are congruent?

OpenStudy (dan815):

okhi sorry i was busy

OpenStudy (dan815):

i will show you the triangles that i think are congruent i might be getting coneection wrong.. but i keep counting 6

OpenStudy (anonymous):

Look at the corresponding sides of the triangle....

OpenStudy (anonymous):

Tangents from a circle to a point are equal in length
