Yes
check:
the sum of the two length sides > the 3rd length side
the difference of the two length sides < the 3rd length side
divide the number of sides by 171
40 sides
A shape with an interior angle of 171 degrees is a polygon, specifically one with a high number of sides. For instance, a polygon with 171-degree interior angles could be a 12-sided polygon (dodecagon) or any polygon with more than 12 sides. The interior angle can be calculated using the formula ((n-2) \times 180/n), where (n) is the number of sides, and 171 degrees indicates that the polygon must have at least 12 sides to accommodate such an angle.
no, these are the first 20 triangle numbers: 1 3 6 10 15 21 28 36 45 55 66 78 91 105 120 136 153 171 190 210
The interior angle of a regular polygon with x sides is 180(x-2)/x. Rearranging the formula for x, the number of sides for a shape with y angles is 360/(180-y). From this formula, the number of sides is 40.
It has 40 sides 180-171=9 360/9=40
divide the number of sides by 171
40 sides
40 sides
If each interior angle is 171 degrees then each exterior angle is 180-171 = 9 degrees. Sum of all exterior angles (irrespective of number of sides) is 360 degrees So number of sides = 360/9 = 40
It will have 40 sides
171 mm
40 sides
45, 153, 171, 351...
Forty of them.
If it's a regular polygon then it will have 40 sides
no a regular polygon has 360 degrees and it can have 4 or more sides
