Triangle.
It is a quadrilateral, all of whose angles are smaller than pi radians (180 degrees).
The sum of the interior angles of a quadrilateral is 360 degrees (not 180). The sum of the exterior angles is also 360 degrees. Whether the quadrilateral is convex or concave is not relevant.
A polygon with one more vertex than a triangle, which has three vertices, is a quadrilateral. A quadrilateral has four vertices and includes various shapes like squares, rectangles, and trapezoids. It is characterized by having four sides and four angles.
A polygon can be convex, which means Convex Polygon: A polygon that has all interior angles less than 180° Concave Polygon A polygon that has one or more interior angles greater than 180° A Complex polygon is neither convex or concave. A star polygon is an example of a complex polygon. If you look in google images, there are tons of pics of them.
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
A quadrilateral, pentagon or hexagon.
It is a quadrilateral, all of whose angles are smaller than pi radians (180 degrees).
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.
No polygon can have a sum of interior angles less than 180 degrees.
A quadrilateral has 4 sides anda hexagon has 6 sides. So the polygon between them is the one that has 5 sides. That is the pentagon.
A polygon and a quadrilateral are alike because they both have more than three sides.
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
The sum of the interior angles of a quadrilateral is 360 degrees (not 180). The sum of the exterior angles is also 360 degrees. Whether the quadrilateral is convex or concave is not relevant.
A polygon with one more vertex than a triangle, which has three vertices, is a quadrilateral. A quadrilateral has four vertices and includes various shapes like squares, rectangles, and trapezoids. It is characterized by having four sides and four angles.
A polygon that has interior angles less than 90 degrees is typically referred to as a "convex polygon." In a convex polygon, all interior angles are less than 180 degrees, and hence, they are also less than 90 degrees. Examples of convex polygons include triangles, squares, pentagons, hexagons, and so on, where all angles at each vertex are less than 180 degrees.
No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 angles.
A polygon can be convex, which means Convex Polygon: A polygon that has all interior angles less than 180° Concave Polygon A polygon that has one or more interior angles greater than 180° A Complex polygon is neither convex or concave. A star polygon is an example of a complex polygon. If you look in google images, there are tons of pics of them.
