Answer 1

20)
`\overline{AC} \cong \overline{AC}` by the reflexive property, so SSS

21)
`\overline{CD} \cong \overline{CD}` by the reflexive property, so ASA

22)
`\overline{CE} \cong \overline{CB}, \overline{AC} \cong \overline{CD}` by the definition of a midpoint and
`\angle 1 \cong \angle 2`, so SAS

23)
`\overline{AC} \cong \overline{AC}` by the reflexive property, so ASA
