How many triangles are in a 20 sided polygon?
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
Each exterior angle of a regular polygon measures 20 How many sides does the polygon have?
18
How many sides does regular polygon have when its interior angle measures 160 degrees?
It has 18 sides
If each interior angle is 20 how many sides does the polygon have?
There is no such polygon but if you meant exterior angles of 20 degrees then it will have 360/20 = 18 sides
Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
How many sides does an irregular polygon have if it has 135 diagonals?
Let the number of sides be x and by solving the equation for diagonals 0.5(x*x-3x) = 135 the solution is -15 or 18 and so therefore it has 18 sides irrespective if it is an irregular or a regular polygon
How many diagonals can you draw in a polygon with 18 side?
153 diagonals.
How many diagonals can be drawn from any vertex of a 20-sided polygon?
It is 18 diagonals
How many sides does a 2880 polygon have?
A polygon whose interior angles are 2880 degrees has 18 sides.
If the exterior angle of a regular polygon is 20 how many sides does the polygon have?
It has 360/20 = 18 sides
How many sides does a polygon have if its exteroir angles are 18 degrees?
360/18 =20 sides.
If each angle of a polygon is 160 degrees how many sides does it have?
18 sides
How many triangles are in a 20 sided polygon?
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
How many sides does a regular polygon have if the measure of an exterior angle is 18?
360/18 = 20 sides
How many sides does a regular polygon have if the measure of an angle is 160?
No regular polygon has 160. The "smallest" polygon is the triangle, which has 180o. ^^FALSE!!!!!!! this polygon has 18 sides!
How many sides does a regular polygon have that has an angle of rotation equal to 18 degrees?
If you mean a polygon with equal exterior angles of 18 degrees then it will have 360/18 = 20 sides.
If a polygon has an exterior angle of 18 how many sides does it?
360/18 =20
