Answer:

3. m<GHF= 90 degrees

4. m<DGH= 45 degrees

5. HF=5

6. DE=50

Step-by-step explanation:

3. The measure of angle DGF and EFG are 45 degrees each and 45+45 is 90 degrees. When you subtract 90 from 180, you get 90.

4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles. This means that angle DGH is half of angle DGF and 90/2=45.

5. The diagonals of a square are congruent so it is also 5.

6. You use the Pythagorean Theorem and 5^2 + 5^2=50

The diagonals of square DEFG intersect at H. The measure of the following option; 3. m∠GHF= 90 degrees. 4. m∠DGH= 45 degrees 5. HF=5 6. DE=50

What is the property of a square?

That rectangle whose all sides are equal is called a square.

A square is always a rectangle, parallelogram, a rhombus, and a quadrilateral but its reverse statement may or may not be true.

(ie it is not always necessary that a rectangle is a square or a parallelogram is a square or a rhombus is a square).

The diagonals of square DEFG intersect at H.

Given that EH = 5, we need to find the measure of the following option;

3. The measure of ∠DGF and ∠EFG are 45 degrees each .

The sum of the angle of the bisector of diagonal 45 + 45 = 90 degrees.

When you subtract 90 from 180, you get 90.

4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles.

This means that ∠DGH is half of ∠DGF

90/2 = 45.

5. The diagonals of a square are congruent so HF is 5.

6. By Pythagorean Theorem
