Triangle XYZ is transformed to create triangle X'Y'Z'. The side lengths of both triangles are shown.

Side length X Y = 10 cmSide length X prime Y prime = 10 cm

Side length Y Z = 9 cmSide length Y prime Z prime = 9 cm

Side length Z X = 4 cmSide length Z prime X prime = 4 cm

Is this a rigid transformation?

other answer is correct. i had used the radius of the radius somehow. a website:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
