forma
1 let points a, b, and
triangle
given
2. let de be a line passing
through 8, parallel to ac
with angles as labeled
defining a parallel line and labeling angles
4. m1 = mz4, and
m23 = m25
congruent angles have equal measures
5. m24+ m_2 .m25 = 180°
angle addition and definition of a straight angle
substitution
6. maim22m23 = 180°
