What is a segment i've been stuck on this question i am grade 7 and new to geometry

im not sure f the correct definition but this is how you would work a question out

The Area of a Segment is the area of a sector minus the triangular piece

There is a lengthy reason, but the result is a slight modification of the Sector formula:

Area of Segment = θ − sin(θ) 2 × r2   (when θ is in radians)

Area of Segment = ( θ 360 × π − sin(θ)2 ) × r2   (when θ is in degrees)

c) yes, because of asa or aas
