A scalene triangle
No - the interior angles of a polygon must total at least 360 degrees.
A regular polygon has all its angles equal AND all its sides equal. A nonregular polygon has at least one angle or one side that is different from the others.
Irregular polygons have three or more straight sides forming the boundaries of the polygon. At least one of the sides or one of the angles is different from the others.
Any polygon can have at least one right angled - for example a right angled triangle. An example of an irregular polygon with only right angles is a rectangle.
At least three of each.
It has at least two sides of different length or at least two angles of different measure.
No - the interior angles of a polygon must total at least 360 degrees.
A regular polygon has all its angles equal AND all its sides equal. A nonregular polygon has at least one angle or one side that is different from the others.
It is called a quadrilateral. This is the general term for a four-sided polygon, but if at least two sides are equal or two angles are equal, it has a more specific name.
Irregular polygons have three or more straight sides forming the boundaries of the polygon. At least one of the sides or one of the angles is different from the others.
Any polygon with at least 7 sides CAN have 5 right angles.
Any polygon can have at least one right angled - for example a right angled triangle. An example of an irregular polygon with only right angles is a rectangle.
A Polygon is a figure with at least three straight sides and angles, and typically five or more.
At least three of each.
3, it's called a triangle.
The angles between adjacent sides of a polygon that are interior to the polygon. If the polygon is convex, the interior angles are always less than 180 degrees. If it is concave, at least one interior angle will be greater than 180 degrees.
A concave polygon is a polygon with at least one interior angle greater than 180 degrees. This causes the polygon to have at least one "dent" or indentation in its shape. The presence of these interior angles greater than 180 degrees distinguishes concave polygons from convex polygons, which have all interior angles less than 180 degrees.
