What happens when AC changes

(a)
`\angle ABC` and
`\angle ADC` are formed from points A and C. So, a change in AC will result to a change in the measures of
`\angle ABC` and
`\angle ADC`.

(b)
`\angle ABC` and
`\angle ADC` are in the same segment, meaning that they will always have the same measure
