basic geometry

[cold python]

angle bisectors bisect an angle directly through the middle, meaning the resulting angles will be the same measure. that should help you solve a few of the questions.
a square shape where 2 lines meet indicates a 90-degree angle.
for #15 and #16, all triangle angles must equal up to 180. Since we know that two angle measures are 32 and 90, the last one can be found through some substitution.
for #17, I've attached an image to help you figure it out
