Two vectors OA = a (vectors) and OB = b (vectors) are given. Construct the vectors a+b and a-b, which start from point O.Look at the three cases for ∠AOB <90, ∠AOB> 90, ∠AOB = 90.
Which of these statements are possible?
a) the length of a + b (vector) is less than the length of a-b (vector)
a)|a+b|<|а-b|
b)|а-b|>|a| and |a-b|>|b|
c) | a + b | = | a-b |
**NOTE: "a" and "b" are vectors
answer: all 3 are possible
I don't know where to start... I would appreciate any help ASAP since they are for tomorrow.
Thank you in advance
