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 pretty wierd shape
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
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....
