Morley's theorem is applied inner angles on triangles and squares, in this paper will be developed Morley's Theorem Using the outer angle on triangles and squares (rhombus, kite and trapezoid foot). In any triangle, the Morlay theorem using an outer angle produces an equilateral triangle and the isosceles trapezoid produces an the kite. The proof in this paper uses a simple method with the concept of kekongruenanan and trigonometry concepts.
