triangle
Any shape that has more than 4 sides has all angles bigger than 90 degrees.
Any closed shape can have angles greater than 90 degrees. A triangle doesn't need to have any, but it can have one of them if it wants to. A shape with four sides doesn't need to have any, but it can have 2 or 3 of them if it wants to. Shapes with more than 4 sides must have some.
A triangle has three sides and three angles that total 180 degrees.
If the interior angles add up to 72000 degrees then the shape has 402 sides
A square
A rhombus
The four inside angles add up to 360 degrees.
It could be a heptagon which has seven sides and a total of 900 degrees of interior angles.
364
The whole shape has 540 degrees in it. To work out the amount of degrees in any shape - total degrees in shape = ((180 x number of sides of shape) - 360)
A shape has three sides if its interior angles add up to equal 180 degrees.
The interior angles of a regular polygon must be 60 degrees or greater.
