Question 35703: Triangle Validity from Explicit Conditions

Original question and givens

The three points in order are N, P, R; the prompt explicitly states that they are noncollinear. Using only the distinctness and noncollinearity conditions, do they form a nondegenerate triangle?

• G001 — The three points in order are N, P, R; the prompt explicitly states that they are noncollinear. Using only the distinctness and noncollinearity conditions, do they form a nondegenerate triangle?

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

• mko-triangle

Step-by-step derivation

source roles = [qf-triangle-explicit-validity, [noncollinear, operation, vertices]]

derived = [triangle, validity, null]

source roles = [[N, P, R], Yes]

derived = [[N, P, R], Yes, Yes]

Result

Yes

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
