How do you rotate a morph by degrees

I am trying to rotate an instance of a [Transformation morph]. I am sending an "angle:" message, which should work since "angle:" is listed as a method in it's parent class, yet when I sent a message, it claims "it does not understand #angle". Shouldn't messagepassing forward the message to it's parent class?

Yes. Perhaps if you pasted the exact code causing the error and a screenshot
of the error it would help. Just a shot in the dark: you said "it does not
understand #angle", but the message is #angle: (added colon)

Did you mean "TransformationMorph"?

I just tried the one-liner below in Pharo 7 (64b Linux) and it worked

(TransformationMorph new asFlexOf: ('Hello' asMorph)) angle: (Float pi /
4); openInHand.

Yes, that "addFlexOf" thing seems to be the message I needed to add to get the morph to rotate. Forgive the naive question.
