Choose a room you'd like to decorate:
*I chose my bedroom*
Measure the length of one wall in inches: 72in.
2. Choose a size of paper to use.
*I recommend the standard 8.5in by 11in paper* Then fold it diagonally and cut it to make a square.
*Once you cut off the bottom portion of the rectangular, the sides of the square will be 8.5in.
3. Cut the square in half along the diagonal to form two paper triangles. These will be your pennant flags.
4. Measure the diagonal of the triangle:____________________
Use the Pythagorean theorem* (a^2+b^2=c^2)to determine the length of the diagonal (hypotenuse):______________________________________________________________________________________
*Your actual measurement and your Pythagorean Theorem answer should be the same or similar.
5.Divide the length of the room (measurement from step1), by the length of the hypotenuse:_________________________________________________________________________________________________________________________
*That is how many triangles you will need to create your string of pennant flags.*
How many flags will you need to cover the entire length of the wall?__________
*the diagonal of the triangle is called the hypotenuse. plug the measurements of the two walls for a and b.*
I am so confused and i need help LIKE ASAP!!!! PLEASE !!!!
To find the length of the diagonal (hypotenuse) of each triangle, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, you have a right triangle where the two sides are 8.5 inches. Let's call one side "a" and the other side "b". Thus, we can set up the equation as follows:
a^2 + b^2 = c^2
Since both sides are the same length (8.5 inches), the equation becomes:
8.5^2 + 8.5^2 = c^2
Solving for c, we get:
72.25 + 72.25 = c^2
144.5 = c^2
Taking the square root of both sides, we find:
c = √144.5
c ≈ 12.02 inches
So, the length of the diagonal (hypotenuse) of each triangle is approximately 12.02 inches.
To determine the number of flags needed to cover the entire length of the wall, divide the length of the wall (in inches) by the length of each flag (hypotenuse). In this case, divide 72 inches (length of the wall) by 12.02 inches (length of each flag):
72 / 12.02 ≈ 5.99
Since we can't have a fraction of a flag, round up to the nearest whole number. Therefore, you would need 6 flags to cover the entire length of the wall.
