1,2 correct.
3. Check how many lines of symmetry a square has!
4. correct.
5. correct.
6. A trapezoid does not have a line of symmetry along its diagonal, and it does not have 3 of its angles congruent. Try something else.
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.
This is what I came up with for this the answer is Rectangle and Square
Mystery #4.
1. The mystery shape has at least 2 congruent sides. 2. It has fewer than 2 obtuse angles. 3. It has more than 1 line of symmetry. 4. It has at least 1 actue angle.
This is what I came up with for this answer is Equilateral triangle
Mystery #5.
1. The mystery shape has at least 2 lines of symmetry. 2. It has no pairs of perpendicular sides. 3. It has more than 3 congruent angles. 4. It's total angle measure is between 180 degrees and 720 degrees.
This is what I came up with for this answer is Regular Pentagon
Mystery #6.
1. The mystery shape has at least 2 lines of symmetry. 2. At least 1 of its diagonals is also a line of symmetry. 3. It has at least 1 obtuse angle. 4. At least 3 of its angles are congruent. 5. It's total angle measures is between 100 degrees and 1000 degrees.
This is what I came up with for this answer is Trapezoid

Three is suppose to be rectangle and square, and six is either regular hexagon or regular octagon
3. Rectangle is correct, but...
"The mystery shape has fewer than 3 lines of symmetry."
Would that include a square?
6.
"It's total angle measures is between 100 degrees and 1000 degrees."
Check total interior angles for hexagon and octagon.

"It's total angle measures is between 100 degrees and 1000 degrees."
Check total interior angles for hexagon and octagon.
Okay I see that a hexagon has 6 sides and total angle measure 720 degrees. A octogon has 8 sides and the total angle measures 1080 degrees. the answer to number 6. is a regular hexagon.
Great! Regular hexagon is correct for #6.
