The minimum number of rigid transformations required to show that polygon ABCDE is congruent to polygon FGHIJ is 2 (translation and rotation).
A rotation translation must be used to make the two polygons coincide.
A sequence of transformations of polygon ABCDE such that ABCDE does not coincide with polygon FGHIJ is a translation 2 units down and a 90° counterclockwise rotation about point D
Let a be the number of trumpet players Let b be the number of saxophone players --------------------- (1) a = b-10 (2) b =3a ---------------- Substitute (2) into (1) (1) a =3a-10 (1) 2a =10
(1) a = 5and (2) b = 3(5)(2) b = 15 ------------------ There are 5 trumpet players and 15 saxophone player
