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
How do you calculate the internal angle of a decagon?
The internal angle of any polygon with n sides is equal to (n - 2) x 180 / n degrees. For example, each internal angle of a square is equal to (4 - 2) x 180 = 360/4 = 90 degrees.
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.
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.
Are two regular decagons similar?
Yes 2 ten sided regular decagons can be similar or congruent to each other
Does a decagon tessallate?
There are decagons which will tessellate.
What are the shapes with 10 sides?
They are decagons.
What is the external angle of a triangle?
360 degrees take away the internal angle
What is the external angle if the internal angle is 135 degree?
180-135 = 45 degrees
