Question

I need help?Thank you!

Answer 1

Given that,

`m\measuredangle1\cong m\measuredangle4`

Since, the opposite angles are equal,

`m\measuredangle4=m\measuredangle2`

From these two equations,

`m\measuredangle1\cong m\measuredangle2`

Since, the opposite angles are equal,

`m\measuredangle1\cong m\measuredangle3`

From, tese two equations,

`m\measuredangle2\cong m\measuredangle3`

Hence, Proved.
