No, you do not need "at" before "angle". You already have used a preposition, "from" and "at" in the sentences. "at an angle" is the prepositional phrase, with the adjective "unusual". The same for the other two sentences.
All three sentences are correct as you have written them.
1. The photo was taken from an unusual angle.
2. The photo was taken at an unusual angle.
(Which preposition do we have to use? Are both OK?)
3. Bend your knees and bend your body at 45 degree angle.
4. Bend your knees and bend your body from 45 degree angle.

1 and 2 -- both are OK.
3 and 4 -- both need "... a 45-degree angle."
The prepositions are OK.

Scroll down a bit and read Hyphens have other uses section. The hyphen I used above fits the "a" use.
-----------
1-1. The photo was taken from an unusual angle.
1-2. He took the photo from an unusual angle.
1-3. He took the photo at an unusual angle.
(Are they all grammatical? Don't we have to use 'at' before 'angle'?)
