m DAB= 32 deg half angle theorm for interior angle and chord
m Arc CD= 141 central angle theorm
m Arc CA=64 parallel lines
m CDA= 32 deg parallel line characteristic
m Arc AB= 91 sum of arcs=360

m angleDAB = 0.5 * m arcBD = 0.5 * 64 = 32
m arc CD = 141 (it is a central angle)
m arc CA = m arc BD = 64
m angle CDA = mDAB = 32 (alternate interior angles are =)
m arc AB = 360 - (64 + 64 + 141) = 360 - 269 = 91
