There is no three-sided shape with two obtuse angles, because the three interior angles of a three-sided shape, which is a triangle, add up to 180 degrees, and two obtuse angles would be over 180 degrees.

No, not if it is a randomly-drawn 8-vertex shape. Octagons only have all- obtuse angles if it is a regular octagon, like the shape of a stop sign.

It depends on they type of arrowhead you have. If it is a arrowhead in the shape of a directional arrow, there are no obtuse angles. The most possible obtuse angles is 1.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. In addition there are concave octahedra. Some of these will have no obtuse angles, others will have several.

2 obtuse and 2 acute in the classic kite shape.

There is no polygonal shape which has exactly those angles. It is possible for a concave polygon with 6 or more vertices to have the given angles.

Hexagon

A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.

a pentagon

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.

Regular octagon has 8 angles of 135o.

A traditional kite shape (a point at the top, then widest about 1/3 of the way down, then tapering to another point at the bottom) has one, two or three obtuse (>90 degree) angles. The two angles at the widest point, about 1/3 of the way from the top, are generally obtuse, but don't have to be. The bottom angle is almost never obtuse. The top angle is sometimes obtuse. So if the top angle is obtuse but the side angles are not, a kite shape has one obtuse angle. If the top angle is not, but the side angles are, it has two obtuse angles. If the top and side angles are obtuse it has three.

A Hexagon has 3 pairs of parallel line and all angles are obtuse.

A square

With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.

An irregular dodecagon.

The shape could be a parallelogram (including a rhombus). Some kites would satisfy these requirements. And it is, of course, possible to have a shape with 5 or more vertices (i.e. more than 4 angles) that contains two acute and two obtuse angles.

All the angles in an octagon are obtuse. (Obtuse means greater than 90 degrees.)

There can be 0 to 5 right angles, or 1 to 6 obtuse angles in a hexagon.

There are 6 obtuse angles in a regular hexagon that add up to 720 degrees.
