your in geometry class and they are doing other type of math dealing with cosines, tangents, etc

That's geometry.

Trigonometry is a subsection of geometry.

well trig isn't geometry

It's a branch of geometry.

Read the actual page you took that quote from.

ur trying to say what they are doing is invalid with bad defintions

just because of your lack of the math doesn't invalidate it

No, I'm saying it's inconclusive, since only one or two points are used.

it works with trig

you miss that red rhetoric was the one doing the math for the globe

they took his math and modified it for flat earth

its not even their math, its red rhetorics math

if you don't think it was done right, take it up with red

Yes. They also completely missed the whole point of Red's video.

he's a globe believer

I think u missed the point

doctor, he never actually reads the things he quotes

I watched the videos

he assumes he is right, and uses that to ignore everything else

the basic geometry on day 1 teaches taht you tkae 2 points to draw a line

3 points to define a plane

Red's video was in response to one by Jeranism. In that video, Jeran claimed that the distance and size of the Sun were randomly chosen, and that the only way you could determine the actual distance was by guessing, since scale invariance makes it impossible to tell between a small, close thing and a distant, large thing. Red corrected him by explaining the trigonometry used to calculate the distance to the sun. It had nothing to do with proving the shape of the Earth, it was simply to correct him on his methods.

4 points to definite 3 dimensions

when your dealing with trig they move way beyond that

Etc. To figure out where something is in 3D space, you need three points.

they are dealing with apparent size

did you watch the video?

Yes. Apparent size is scale invariant, you can't tell just by looking whether it's near or far.

That was the point of the first video, and Jeranism's video that Red was responding to.

Red corrected Jeranism in that you can use other methods besides eye-balling to determine distance.

Then Globebusters responded to Red's video, missing the point completely, accusing Red of assuming the Earth is a globe, when all he was doing was correcting Jeran on his methods.

I've watched people do the math

I must agree with the18thdoctor

those videos are highly irrational

gotta work on that trig

using pythagorean theorem they calculate the distance of the sun at 93,000,000 miles away

but they assume we live on a curve to get that distance
