If triangle 3 is joined with another triangle that is the same size and shape, do the two triangles always form a square? construct a math argument to explain your reasoning (only if you know)

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′.

Use the given information to determine the exact trigonometric value.
