Referenced from lesson Defining Functions (Spring, 2021)

Highlight the variables in gt and label them with the word "size".

(EXAMPLE (gt 20) (triangle 20 "solid" "green")) (EXAMPLE (gt 45) (triangle 45 "solid" "green"))

(define (gt size) (triangle size "solid" "green"))

Highlight and label the variables in the example lists below. Then, using gt as a model, match the examples to their corresponding function definitions.
