Question

If
BT ≅ EU , BU ≅ ET , prove: ∠B ≅ ∠E.

Answer 1

`</p><p>\begin{cases}</p><p>BT\approx EU \\</p><p>BU\approx ET</p><p>\end{cases}</p><p>`

If
`B\approx E` then

`</p><p>\begin{cases}</p><p>BT\approx BU \\</p><p>BU\approx BT</p><p>\end{cases}</p><p>`

Or simply

`BU\approx BT`

Since
`BU\approx BT` we obtain that
`U\approx T` hence
`B\approx E` must apply for the aproximity to stand.

Hope this helps.
