Not sure that it has a name.
Start with a square standing on a vertex. Cut of the top and bottom vertices with horizontal lines. The shape will resemble one isosceles trapezium sitting on its short side and supporting an inverted congruent isosceles trapezium.
Yes the interior angles of a regular octagon are obtuse.
An iscoceles triangle that is either obtuse or acute
a pentagon
A quadrilateral with equal sides and no right angles is called a rhombus. In a rhombus, all four sides are of the same length, but the angles can vary, typically being oblique (either acute or obtuse) rather than right angles. This shape maintains symmetry and has diagonals that bisect each other at right angles, but the angles themselves are not right angles.
a pretty wierd shape
octagon
It is a trapezoid and its other 2 angles are obtuse and acute
Oh, honey, that's an obtuse trapezoid for you. Two obtuse angles and no lines of symmetry, just like a rebellious teenager breaking all the rules. It's a unique shape that likes to stand out in a crowd, not conforming to the symmetry standards.
Yes the interior angles of a regular octagon are obtuse.
An equallateral triangle ~ID1533681184 Sorry ID1533681184 but and equallateral triangle does not have three lines of SYMMETRY, it has three line segments. ~EEE2

Impossible.
no....
