post an image?

OpenStudy (anonymous):

ya

OpenStudy (anonymous):

let me see if I can

OpenStudy (anonymous):

k

OpenStudy (anonymous):

we know: BC=AD, AB=CD, angles 2+3=180 deg, angles 1+4=180 deg

OpenStudy (anonymous):

so thats why they are congruent?

OpenStudy (anonymous):

AC must equal itself. Therefore the triangles ABC=ADC.

OpenStudy (anonymous):

thank you very much

OpenStudy (anonymous):

i got Abc=ADC also

OpenStudy (anonymous):

Because all sides are equal. That proves angles 4=2 The same can be done with triangles DAB=DCB or you can use supplementary angles to prove angles 1=3

OpenStudy (anonymous):

Each individual side has an equal. (not equilateral triangle, sorry if this was confusing)

OpenStudy (anonymous):

Thank you so much, you really helped understand :)

OpenStudy (anonymous):

your welcome

how can I give you more points? for your good answer
