octagon
Opposite sides are equal in length. Opposite angles are equal. It is also known as a parallelogram.
No but it has 2 equal acute angles and 2 equal obtuse angles
It could be a right angle trapezoid whereas the other two angles are acute and obtuse
The 4 interior angles of a trapezium add up to 360 degrees and if it's an isosceles trapezium it can have 2 equal obtuse angles and 2 equal acute angles
Yes, a regular hexagon has ALL sides the same length and ALL angles equal. If you flatten it somewhat (like the profile of a lens) then the sides may still have the same length but some angles will be larger than others if opposite angles are the same than there will be symmetry. (there are many other options to retain symmetry in a hexagon this is but one)
Impossible.
An equallateral triangle ~ID1533681184 Sorry ID1533681184 but and equallateral triangle does not have three lines of SYMMETRY, it has three line segments. ~EEE2
Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.

An obtuse triangle can have no right angles, and has two equal angles.
No because it has 2 equal interior acute angles and 2 equal interior obtuse angles but its 4 sides are equal in length
56678 Shape is called a rhombus
No but it can have 2 equal opposite obtuse angles and 2 equal opposite acute angles
Opposite sides are equal in length. Opposite angles are equal. It is also known as a parallelogram.
An iscoceles triangle that is either obtuse or acute
No but it has 2 equal acute angles and 2 equal obtuse angles
