On a piece of paper, use a protractor to construct right triangle def with de=4 in. , m∠d=90° , and m∠e=45° . what statement is true about the triangle? df=4 in. ef=4 in. df=2 in. ef=7 in.

  The answer is DF=4 inch.

Step-by-step explanation:  As shown in the attached figure, a right-angled triangle DEF is constructed using a protractor, where ∠D=90°, DE 4 inch and ∠E=45°.

So, according to the figure, EF is the hypotenuse of the triangle.

Now, in ΔDEF

∠D + ∠E + ∠F = 180°, which gives us

∠F = 180°-∠D - ∠E = 180° - 90° - 45° = 45°.

Hence, ∠E = ∠F. Thus, DE = DF, which implies that ΔDEF is an isosceles triangle also.

Thus, DF = 4 inch.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
