The other names for ∠1 are; ∠PFY, ∠YFP, ∠F
This is about naming angles in the right manner.
Now, when naming angles, the point at which the angle is located will be in the middle of the 3 letters we will write. Looking at the given image, ∠1 is an angle formed at Point F by the intersection of two lines namely Line PF and Line YF. From the earlier, definition about how to name angles, we see that ∠1 is formed at point F. Thus, we can name this angle starting from the left as ∠PFYSimilarly, we can also name this angle starting from the right as ∠YFP for the same reasons listed in naming it from the left. Lastly, we can also name this angle as ∠F because F is the point where the angle 1 is formed.The right names for ∠1 are; ∠PFY, ∠YFP, ∠F
