0° of angle from the flat ground

[GoldfishLord]

What's the difference in meaning between "0° of angle from the flat ground" and "an angle of 0° from the flat ground"?

Give us the context. Surely you know you have to do this.

Something that is not tilted is level. 0° of angle from the flat ground.

I wonder if we can use "an angle of 0°" instead of "0° of angle".

That's not context! Why are you trying to use the phrase? Why haven't you given us a complete sentence to consider? Who are you going to be saying/writing this to?

 

[jutfrank]

It seems as if you're saying that you've seen the phrase '0° of angle from the flat ground' written somewhere in a text. Is that the case? If so, tell us where you saw it and who wrote it.

Please don't make us work any harder than is necessary.

Polar clock​

One of Wheatstone's most ingenious devices was the 'Polar clock,' exhibited at the meeting of the British Association in 1848. It is based on the fact discovered by Sir David Brewster, that the light of the sky is polarised in a plane at an angle of ninety degrees from the position of the sun. It follows that by discovering that plane of polarisation, and measuring its azimuth with respect to the north, the position of the sun, although beneath the horizon, could be determined, and the apparent solar time obtained.

Introduction​

​

In Complementary angle there are 90 degrees of angle. An angle is a figure in plane geometry created by two rays or lines with a shared endpoint. The common terminal of two rays is called the vertex, and the two are referred to as sides of an angle. The Latin word "angulus," which translates as "corner," is the basis of the English name "angle."

Are "an angle of ninety degrees" and "90 degrees of angle" interchangeable?

It's clear that the writer of that article thinks so.
