The pentagon ABCDE is a shape that lies in a plane: it’s a closed curve made of 5 line segments.
The 5 points A, B, C, D and E are corners.
The 5 line segments [AB], [BC], [CD], [DE] and [EA] are sides.
The lines [AB] and [BC] intersect in B.
The line segments [AD] and [CE] are diagonals of the polygon.
The lengths AE and AB are equal.
The angle in E is acute whereas the angle in A is obtuse.
