A composition of transformations is... musical isometry written transformations two or more transformations a movie about transformations A glide reflection is shown below. A glide reflection is... a rotation + a translation a reflection + a translation a reflection + a rotation two reflections An isometry is a transformation in which the original figure and its image are congruent. Examples of "rigid transformations" include translations, reflections, and rotations. True or False: A composition of two rigid transformations is an isometry. True False A composition of two reflections across two parallel lines is equal to: a reflection a rotation a translation a dilation A composition of two reflections overintersecting lines is equivalent to... a reflection a rotation a translation a dilation Which composite transformation maps ∆ABC onto ∆A''B''C'' T<8, -2> ○ R180º T<14, 3> ○ T<-6, -5> T<14, 3> ○ ry-axis T<14, 3> ○ >T><8, -2> ∆ABC undergoes ry-axis, then T(x,y) → (x, y-3) Find the coordinates of A' and A'' B C A (-2, 2) y x A''= (-1, 2) A''= (-1, -2) A''= (2, -1) A''= (-2, -1) A'( , ) ∆ABC undergoes rx-axis then T<-4, 3> Find the coordinates of A' and A'' C B (5, 4) A A'( , ) A''= (5, -4) A''= (-9, 7) A''= (1, -1) A''= (1, 3) ∆ABC undergoes R180 then undergoes T<2, 2> Find the coordinates of C' and C'' (-6, -1) B C A C'( , ) C''= (8, -1) C''= (8, 3) C''= (6, 1) C''= (4, -1) ∆ABC undergoes a composite transformation: T(x,y) →(x-3,y-1) ○ R90 (ccw)Find the coordinates of A' and A'' B C (7, 2) A A' ( , ) A''= (-2, 7) A''= (-1, 6) A''= (-5, 6) A''= (-1, -8) ∆ABC undergoes a composite transformation: ry-axis ○ R90 (ccw) Find the coordinates of A' and A'' B C A A' ( , ) A''= (0, 3) A''= (-3, 0) A''= (3, 0) A''= (0,-3) ∆ABC undergoes a composite transformation: R180 ○ R90 Find the coordinates of A'' C B A A''= (1, 1) A''= (-1, 1) A''= (0,0) A''= (0,-1) Which composite transformation maps ∆ABC onto ∆A''B''C''?
