- Tim Brzezinski
In the right triangle above, what is the relationship between the blue angle and pink angle? (What vocabulary term/adjective describes the relationship between these 2 angles?)
Fill in the blank with the correct word: The _____________ of the blue angle is the percentage displayed.
Fill in the blank with the correct word: The ___________________ of the pink angle is the percentage displayed.
Thus, we can conclude that if 2 angles are ______________________ (see your answer to (1)), then the __________ of one angle is equal to the ____________________ of its ___________________ ! Notice how the first 2 letters of the last 2 blanks are the same? Why is this?
