Because multiplying 1/2 by 2 will give 1 That will make the eqaution t=-7*2 t=-14

it's asking for a reasoning :/ Reflexive Property of Equality Symmetric Property of Equality Subtraction Property of Equality Multiplication Property of Equality

It's a property of equality (since you're doing something to both sides of an equation)

the question is what are you doing to both sides?
jim_thompson5910
  • jim_thompson5910
it's not a trick question (well I hope it doesn't seem that way)

reflexive?
thesecret20111
  • thesecret20111
I think it is the Multiplication Property of Equality
jim_thompson5910
  • jim_thompson5910
you're reflexing each side?

no your multiplying :D

by 2
jim_thompson5910
  • jim_thompson5910
so it's the multiplicative property of equality
jim_thompson5910
  • jim_thompson5910
that says if you have a = b then you can multiply both sides by c to get c*a = c*b

alright go for it

i think its definition :/ not 100 percent sure though
jim_thompson5910
  • jim_thompson5910
nope it's not that and it's not the symmetric property either
jim_thompson5910
  • jim_thompson5910
when you say "the measure of angle 1 + the measure of angle 2", you are basically adding the two angles because they are adjacent angles, they form a larger angle (think of them glued together)
jim_thompson5910

so which property am I describing?

angle addition -___-

yep

sorry for these really simple questions
jim_thompson5910
  • jim_thompson5910
a lot of these have descriptive names so they are probably deceptively simple
jim_thompson5910
  • jim_thompson5910
its fine, you're just second guessing yourself
anonymous
  • anonymous
i think it might be segment addition
jim_thompson5910
  • jim_thompson5910
no you're still adding angles
jim_thompson5910
  • jim_thompson5910
not segments

lol -___- transitive prop of congruence
jim_thompson5910
  • jim_thompson5910
technically it should be "the definition of complementary angles", but the next best thing is "angle addition postulate" because you're basically exploiting the fact that the two add to 90 degrees

@arkoffusion If you don't know and ask, it is fine. That is how you learn. It is if you don't ask that it is a problem! So don't apologize for simple questions. It is still an important part of learning!
