To mark X spot, the ribbon should be stretched diagonally from one end to another. Since the flag is a square, a diagonal cuts the square into 2 equal triangles. The diagonal length is the hypotenuse of the triangle, as the triangles formed are 2 right angled triangles.
Using Pythogoras' theorem, hypotenuse can be found out with the following equation;
H² = X² +X²
where H is the hypotenuse in other words the diagonal
X - length of the triangle, since its a square all lengths are equal
X- 12 inches
H² = 12² + 12²
    = 144+144 
H² = 288
H = 16.9 inches≈17 inches
to make the mark X he will need 2 strips of ribbons of length 17 inches each.
total length of the ribbon needed = 34 inches

Given that CD¯¯¯¯¯¯¯¯ is a perpendicular bisector of AB¯¯¯¯¯¯¯¯, where D is on AB¯¯¯¯¯¯¯¯, how can you use the Pythagorean Theor
Liula [17]

Answer:

(AD)^2 + (CD)^2 = (CA)^2 and (CD)^2 + (BD)^2 = (CB)^2

Step-by-step explanation:

Given

Bisector: CD

of Line AB

Required

Apply Pythagoras Theorem

From the question, CD bisects AB and it bisects it at D.

The relationship between AB and CD is given by the attachment

Considering ACD

From the attachment, we have that:

Hypothenuse = CA

Opposite = CD

Adjacent = AD

By Pythagoras Theorem, we have

(AD)^2 + (CD)^2 = (CA)^2

Considering CBD

From the attachment, we have that:

Hypothenuse = CB

Opposite = CD

Adjacent = BD

By Pythagoras Theorem, we have:

(CD)^2 + (BD)^2 = (CB)^2
