Which of the following transformations will always produce a congruent figure? A. a dilation by a scale factor of 2, and then a translation
B. a reduction, and then a 90° rotation about the origin
C. a reflection, and then an enlargement
D. a translation, and then a reflection across the x-axis​

Write a function for a rotation 90 degrees counter clockwise about the origin, point 0

In need of in the diagram, ∠abc is a right angle. ∠dbc = 30°27'40". find the measure of ∠abd.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
