Given : <O 67.5°
<P 67°30’
Prove <O = <P
Proof: Since there are 60 minutes in 1 degree, and 30 minutes equals one half a degree, 67°30’ equals 67.5°. Since <O and <P have the same measure, they are =.

Proof:
<DEH is a straight angle. Therefore, a straight < m =180. Then using algebra, m<def + m<FEH = 180 , then m<FEH = 135. Since <‘s with the same measure are =, <FEH and <JKM are = because they are each 135

Given: <D = 90 <E is obtuse
Prove: <D = <E
JUST ONE MORE!!! I PROMISE

Is this conclusion true?
This conclusion is false! Since <E is obtuse, its measure is greater than 90. Since <D and <E have different measures, they are not congruent!
