a quadrilateral
The formula for the sum of the interior angles of a shape with n sides is: 180 * (n - 2) So, for a 31 sided shape, the sum of the interior angles is 180 * 29 = 5,220.
The formula to find the sum of the angles of any shape is: (sideCount-2)*180 If the shape has 11 sides the total interior angle is: 1620.
If the shape is flat is is called a: dodecagon If it is a 3 dimensional object it is called a dodecahedron
Alternate Interior Angles
156 degrees Sum of interior angles of a polygon=180(n-2), where n is the number of sides. To find one interior angle's measure, divide by the total number of angles, which is also the total number of sides.
A Rhombus is a flat shape with 4 equal straight sides. So the answer is that there are four interior angles.
A shape with 7 sides and 7 angles is called a heptagon. A heptagon is a polygon with seven straight sides and seven interior angles. Each interior angle of a regular heptagon measures 128.57 degrees.
The sum of the interior angles of any shape that has straight sides is(180 degrees) times (the number of sides - 2) .For the case of a hexagon, (the number of sides - 2) = 4 .The sum of the interior angles = (180) x (4) = 720 degrees.The sum of the exteior angles is always 360 degrees, no matterhow many sides the shape has.
It depends how many sides the shape has. If n is the number of sides of the shape, then the interior angles sum to (n - 2) x 180o. The exterior angles of any shape sum to 360o.
It is a heptagon that is a polygon having 7 sides with 7 interior angles.
A ten-sided shape is called a decagon. In geometry, it has ten straight sides and ten angles. The sum of its interior angles is 1,440 degrees. Decagons can be regular, with all sides and angles equal, or irregular, with varying lengths and angles.
A square or a rectangle both have 4 sides and 4 interior right angles
Assume each side is a straight line segment. With 3 sides you can make 1 triangle with a sum of interior angles = 180°. With 4 sides you can make 2 triangles with a sum of interior angles = 2 x 180° = 360°. With 5 sides you can make 3 triangles with a sum of interior angles = 3 x 180° = 540°.
They are angles between adjacent sides of the polygon, measured on the inside of the shape.
