Question

Please can someone help????

Answer 1

Proof:

Consider
`\triangle WXZ, \triangle YZX:`

`\overline W\overline X = \overline Y\overline Z` (given)

`\angle WXZ = \angle YZX` (alternate angles are equal,
`\overline W\overline X\parallel \overline Y\overline Z`)

`\overline Z \overline X` is a common side

∴
`\triangle WXZ \cong \triangle YZX` (SAS)

Hope this helps :)
