Me me with my math

iris has two ribbons. the first ribbon is 11.7 in. long. the second ribbon is 5.25 in. long. she wants to cut them so that they are the same length.
(a) estimate the difference between the ribbon lengths.
(b) will your estimate be high or low? explain.
(c) how much does iris need to cut from the longer ribbon to make the ribbons the same length?

A. I would estimate that 7 in of the ribbon
B. the estimate would be high because the longer the ribbon is the more of the ribbon would have to be cut.
C. 11.7 - 5.25 = 6.45 iris has to cut 6.45 off the longer ribbon for the ribbons to be the same length.

Example 1 was created by following the constitution step correctly.

Step-by-step explanation:

If you compare both figures, you would see that Example 1 shows an actual bisector, while Example 2 doesn't. Basically, you can deduct this by observing the simmetry around the bisector.

Remember that a bisector is a line which divide an angle in two equal parts, and the Example 2 doesn't show that. That's why Example 2 wasn't created by following the constitution steps correctly.

Therefore, Example 1 was created by following the constitution step correctly.
