Question

Overline MD cong overline LS additional information is necessary to show that triangle MTD cong triangle LGS by SSS?

Answer 1

`TD \cong GS`

Explanation:

See comment for complete question

Given:

`TM \cong GL`

`MD \cong LS`

Required

The information that shows
`\triangle MTD \cong \triangle LGS` by SSS

By SSS implies that, the three sides of both triangles are congruent

Already, we have:

`TM \cong GL`

`MD \cong LS`

The third side of
`\triangle MTD` is
`TD`

The third side of
`\triangle LGS` is
`GS`

So, for both to be congruent by SSS, the third sides must be congruent

i.e.

`TD \cong GS`
