So which direction would the ball end up going after a 90º lip out?
Work that out, then go another 90º.

90 degrees = left
180 degrees = straight on
270 degrees = right
360 degrees = back at you

Blimey I thought my understanding of the of geometry wasn't great but you are having "a 'mare".

So what if the ball went 90º right?

270.

There is, just you go right ahead and do it.

...it definitely isn't a 180.
...

Oh yes it is! Offset (left or right) by something approxinately the width of the hole!

To confirm, go find a protractor (if such things can be found these days) and place the straight edge across the hole (so that the 90 degree line is in the direction of the ball). Note where the 'zero' line is pointing (90 degrees left of the ball's original direction). A further 90 degrees, equating to the 'horseshoe' (= direction changed 180 degrees in total, position offset by about the width of the hole!) would mean the ball is travelling back in the direction it came from!

Edit. As per Slime's explanation!

So, a ball can't turn 90º right ....................... interesting.

270.

Nope, 90º.


If you're walk a few feet due north and turn to face due east, how many degrees is that? It's 90º.
If you then turn another 90º to the right, you're now facing due south after turning a total of 180º and you're facing the direction you came from.
It really is that simple in my head.

Christ is this still going on

its pretty simple isnt it

If a ball goes round round the hole then it travels round 360 degrees of the hole "BUT" its direction of travel changes by 180 degress

So we agree, it's done a 180º horseshoe ....................... glad you cleared that up .
Oh, and it doesn't travel round 360º of the hole, it would then have to go in at the front and come out of the hole at exactly the same spot it entered.

Absolute tosh!

Why would the 90 degrees line represent the direction of the ball?

90 degrees represents a right angle not a straight line.

 

[Deleted member 18588]

For the purposes of calculating the angle of the direction of the ball's travel it would be assumed that it entered the circle (cup) from 0 degrees.

Therefore, a left turn equates 90 degrees, straight on is 180 and a right turn 270.

That leaves 360 for a complete circuit.

I recommend using a complete protractor to assist in the calculation rather than the more common semi-protractor.

Wrong, just wrong.

When a golfball horseshoes out of the cup, straight back at the golfer, and it's described as a 360º .................................... when it just isn't, it's a 180º!!

Well sadly you're wrong, it's holes in one. Just as the plural of surgeon general is surgeons general.

Geometry isn't my strong suit by I would say it's a 360.

180 would be straight on leaving the hole directly between the player and the ball.

I'm with Slime.
A 360 has to go all the way around the hole and carry in in the original direction..

How many degrees would it have to travel to come back to the player??
360 in a full circle?? 180 would see it behind the hole ?

That would be a 540?

Scientifically speaking, it's probably somewhere between 180 and 360 degres... It almost certainly isn't a full 360 and it definitely isn't a 180.

See my picture labelled with the angles and with a rough ball direction in green to show the direction of the ball circumnavigating the hole and how it travels through the angles on the circle. In my case it enters around 30 degrees and leaves at about 290 so it would be a 260 degree turn.


But we use 180 figuratively to mean a reversal, which is why people say 180. They're applying a figurative notion to reality incorrectly.

Did u draw the diagram?? That’s dedication. 👍👍👍👍

I did indeed.

How many degrees in a circle?

If the ball returns (give or take) to where it first hit the lip it has completed a circle I.e
360 degrees.

So which direction would the ball end up going after a 90º lip out?
Work that out, then go another 90º.

Agreed! But it hasn't 'completed a circle'! Ir has only 'completed an about face', which is half a circle. A full circle would have the ball travelling in the same direction as it was struck - not in the reverse direction (aka horseshoe)!

Absolute tosh!

90 degrees represents a right angle not a straight line.

Perhaps you should actually look at a (180 degree) protractor to see what I mean. You don't seem to have grasped my (possibly not crystal clear) explanation.
Here's one https://www.discountedstationery.co...SHcfh6pKWiXEKiUcPaYIr0CmLnq1xVXMaAoUlEALw_wcB

Ball initially travels along (centre to) (+)90 degree, and ends up 'horseshoeing' - reversing direction - so (offset by hole width) parallel to centre to -90 degree line - which is a 180 degree change of direction. 360 degrees would have ball making a complete circle, subsequently travelling in same direction as originally!

Here's a 360 degree protractor that might clarify if the '180 degree' one requires too much imagination (no criticism intended).
https://www.amazon.co.uk/dp/B003JMJ...t=&hvlocphy=9045844&hvtargid=pla-475870124287

As seen in the pic, ball can be considered to be travelling on 'centre to 270 of outer markings line'. After horseshoe, it's traveling on 90 degree of outside markings - a 180 degree change of direction.
