Using the image shown above, match the angles that have the same measure. Picture: https://s3.amazonaws.com/platocdn/EdAssets/a471b555b7b64af1b8efdebc8b00d391?ts=635047130705900000

OpenStudy (michele_laino):

hint: the triangle CDE is an isosceles triangle, so the angles DCE and DEC are congruents

OpenStudy (anonymous):

So they match?

OpenStudy (michele_laino):

namely their common mesure is (180-54)/2=...?

OpenStudy (michele_laino):

yes!

OpenStudy (michele_laino):

what is their common measure?

OpenStudy (anonymous):

63. So I will put those together.

OpenStudy (michele_laino):

ok!

OpenStudy (anonymous):

Same with GEF and EFG right?

OpenStudy (michele_laino):

we have to update your drawing every time we find the value of an angle

OpenStudy (michele_laino):

no, since the triangle EFG is not an isosceles triangle

OpenStudy (anonymous):

Oh ok

OpenStudy (michele_laino):

angles CEG and CHG are congruent since HGCE is a parallelogram. Their common measure is 108 degrees

OpenStudy (anonymous):

They do not have those as one of the options here are the opitions
