If a quadrilateral has exactly 2 lines of symmetry, and both are angle bisectors, then which statement would be true? the figure must be an isosceles trapezoid because it has 2 congruent base angles. the figure must be a rectangle because all rectangles have exactly 2 lines of symmetry. the figure must be a rhombus because it has exactly 2 pairs of congruent angles. the figure must be a square because the diagonals of a square bisect the right angles.
