The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
A figure is called 'equilateral' when all of it's sides are equal lengths. ie: an equilateral triangle.
If each interior angle measures 170 then it will have 36 sides
Each interior angle measures 128.57 degrees rounded
If each interior angle measures 174 degrees then it will have 60 sides
16 sides
If one interior angle measures 172° then the corresponding exterior angle measures 180 - 172 = 8°. The number of sides = 360 ÷ 8 = 45.
It tells you how many triangles can be made using the figure. For example: A rectangle has 4 sides. The formula for angle measures is (n-2)180. Plug in 4 for n number of sides. (4-2)180 2(180) 360 degrees for all sides 90 degrees for one side
zero
It will have 17 sides
51 sides
The word quadrilateral means having four sides. A four-sided figure has four angles.
