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
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.
1 in = 0.0254m 171 in = 171 x 0.0254 m ~= 4.34m
It has 40 sides 180-171=9 360/9=40
divide the number of sides by 171
40 sides
40 sides
It will have 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
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
