Yes. You can construct a major triad starting from any root note by following the formula: Root + Major Third + Perfect Fifth (e.g., C-E-G, G-B-D, F-A-C).
A power chord (common in rock guitar) typically contains only the root and perfect fifth, omitting the third which determines major/minor quality. A major triad must include the major third.
