It is a 3 sided shape with 3 interior angles that add up to 180 degrees
No because the interior angles of a four sided shape can't exceed 360 degrees.
There is no such shape because shapes or polygons must have 3 or more sides and there are 3 interior angles in a 3 sided polygon which is a triangle that add up to 180 degrees.
The 3 interior angles of a triangle add up to 180 degrees

There are 3 lines of symmetry ina 6-sided shape.
that is a square with a triangle inside turned
The three internal angles add up to 180 degrees.

Well hello there, friend! A 12-sided polygon is called a dodecagon. To find the sum of the interior angles in any polygon, you can use the formula (n-2) x 180 degrees, where n is the number of sides. So, for a dodecagon, the sum of the interior angles would be (12-2) x 180 = 1800 degrees. Each interior angle in a dodecagon would be 1800 degrees divided by 12, which equals 150 degrees. Happy painting!

A 3 sided shape is a triangle. A 4 sided shape could be a square or rectangle.
If you mean a "triangle" it is a 3 sided shape with interior angles adding to 180 degrees and exterior adding to 360 degrees.
