Question

true or false? the measure of angle θ is 1 radian

Answer 1

false. Look into the definition of the radian

Answer 2

thanks i thought so, its false because the arc's length is not equal to the radius, right?

Answer 3

definition of radian
s / r = theta (radians) , s = arclength , r = radius

Answer 4

oh okay. so why would it be false then?

Answer 5

@perl

Answer 6

oh because the arc length should equal the radius, is that right?

Answer 7

theta here is 2/2.5 radians , and that is not equal to 1 , it is 0.8 radians

Answer 8

ohhh okay i see how you did that now. thanks for the help!! so basically just the arc length over the radius and that gives you the value of θ?
