given: ac = ab, cd = de
m∠abc = 70°, m∠ ecb = 35°

prove: de ║bc

m∠acb = m∠ by

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
