Which of the following statements is INCORRECT? APyramid is a solid figure, the base of which is a triangle or square or some other polygon and its side faces are equilateral triangles that converges to a point at the top. BIn geometry, we take a point, a line and a plane as undefined terms. CIf the area of a triangle equals the area of a rectangle and the area of the rectangle equals that of a square, then the area of the triangle also equals the area of the square. DEuclid's fourth axiom says that things which coincide with one another are equal to one another.
