Please let me know if I am right on these.

Mystery #1.

1. The mystery shape has fewer than 3 lines of symmetry. 2. It has at least 1 pair of perpendicular sides. 3. It has at least 1 pair of parallel sides. 4. It has less than 1 obtuse angle.

This is what I came up with for this the answer is Rectangle iwth adjacent sides of different length

Mystery #2.

1. It has fewer than 3 diagonals. 2. It's total angle measure is greater than 180 degrees. 3. It at least has 1 obtuse angle. 4. It has at least 1 line of symmetry.

This what I came up with for this the answer is Rhombus



Mystery #3.

1. The mystery shape has fewer than 3 lines of symmetry. 2. It has at least 1 pair of perpendicular sides. 3. It has at least 1 pair of parallel sides. 4. It has less than 1 obtuse angle.
