Answer 1

Solution:

Given : ∠ D E G= 51°, ∠GEF=39°

To prove: Δ D E F is a right triangle.

Proof:

A right angle triangle D E F.

∠ D E F =90°.

Point G is on segment D F, and segment E G is drawn.

Now, taking ∠DEG and ∠GEF into consideration,

∠DEG=51° and ∠GEF=39°→→(Given)

∠DEG + ∠GEF =

∠DEF=51° + 39°

∠DEF=90°,showing Triangle D E F is a right triangle.

Answer 2

box number one: given

box number two: angle addition postulate

box number three: 51 degrees + 39 degrees = m DEF

box number four: 90 degrees = m DEF

box number five: DEF is a right angle

box number six: definition of a right triangle

just took the test and these are the correct answers, hope i helped :)
