Symmetry

Question 2 • ! MCHS (CR25) - GEOMETRY

If a quadrilateral has exactly 2 lines of symmetry, and both are angle bisectors, then which statement would be true?

Answer
A
The figure must be an isosceles trapezoid because it has 2 congruent base angles.
B
The figure must be a rectangle because all rectangles have exactly 2 lines of symmetry.
C
The figure could be a rhombus because the 2 lines of symmetry bisect the angles.
D
The figure could be a square because the diagonals of a square bisect the right angles.

Explanation

A rhombus has two lines of symmetry along its diagonals, and each diagonal bisects a pair of opposite angles. A square also has diagonal symmetry lines that bisect its angles, but it has four lines of symmetry, not exactly two. So the figure could be a rhombus, while the claims that it must be a rectangle or an isosceles trapezoid are not justified.
