It looks like a square with a triangle on top of it.
it's a trapezoid
It has no particular name but it looks like a house.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A plane figure with at least three straight sides and angles, and typically five or more.
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
A square
a house
a pentagon with two adjacent right angles
A right angle triangle or an obtuse triangle
The maximum number of right angles in a polygon is determined by the formula (n-2), where n represents the number of sides in the polygon. A polygon with n sides can have a maximum of (n-3) right angles, as the sum of interior angles in a polygon is given by (n-2) * 180 degrees. Since a right angle measures 90 degrees, the maximum number of right angles in a polygon is limited by the total number of interior angles.
it's a trapezoid
Any non-regular polygon from pentagon and up can have two or more right angles. Take a square and chop off the top and then make a two more connecting line segments (like a house with roof), and you have an irregular pentagon with 2 right angles at the bottom, for example.
It has no particular name but it looks like a house.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A regular polygon like an equilateral triangle.
A polygon has exactly as many sides as it has angles.
A polygon is a shape in which every site is a line segment. It can have any number of sides and any number of angles, but always has the same number of sides as it has angles..
