How many sides does a regular polygon have if the measure of an angle is 12?
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
Which triangle does have one internal angle of 120 degrees?
An obtuse angled triangle can have can have one internal angle of 120 degrees.
What is the external angle of a triangle?
360 degrees take away the internal angle
1oo sided shape?
3o decagons
If the areas of two similar decagons are 625 ft2 and 100 ft2 what is the ratio of the perimeters of the decagons?
The areas of two similar decagons are in the ratio of 625 ft² to 100 ft², which simplifies to 6.25:1. Since the ratio of the perimeters of similar shapes is the square root of the ratio of their areas, we take the square root of 6.25, which is 2.5. Therefore, the ratio of the perimeters of the decagons is 2.5:1.
What is the internal angle of a regular pentagon?
Each internal angle measures 108 degrees
How many lines of symmetry do decagons have?
Decagons have 10 lines of symmetry i dont know where
What is a decagons?
For anyone who is not a synesthete, a decagon has no specific colour. Individual synesthetes will see decagons in different colours.
What is the measure of one angle of a regular convex 20-gon?
A triangle has an internal angle of 180/3 A square has an internal angle of 360/4 A pentagon has an internal angle of 540/5 An 'x'-agon has an internal angle (180(x-2))/x = (180x-360)/x = 180 - 360/x A 20-agon has an internal angle of 180 - 360/20 = 162
Are the internal angle and external angle of a polygon supplementary?
yes.

Are two regular decagons similar?
Yes 2 ten sided regular decagons can be similar or congruent to each other
What are the shapes with 10 sides?
