Question

Use the square DEFG to find the following:

HF=_____
GE=_____
GF=_____
m<GHF=_____
m<DEF=_____
m<DGH=_____
​

Answer 1

The answer to your question is below

Explanation:

HF = HE = 5

GE = 2HE = 2(5) = 10

GF = EF = 7.1

m∠GHF = 90° because m∠HGF = 45° and m∠HFG = 45° and

the sum of the internal angles in a triangle equals 180°.

m∠DEF = 90° the sum of the internal angles in a square equals 360°

then, 360/4 = 90°.

m∠DGH = 45° because the angle ∠DGF was cut in two equal angles.
