Answer:
1). Fold reflection symmetries = 5
2). Order of rotational symmetries = 10
3). Smallest angle of rotational symmetry = 36°
Step-by-step explanation:
A decagon has number of fold reflection symmetries = 5
[Fold reflection symmetries are the lines by which we can fold the shape into half]
Order of rotational symmetry of a decagon = 10
[Order of rotational symmetry means number of rotations by which the polygon maps itself in a complete rotation of 360°]
Smallest angle of rotational symmetry for a decagon
= 
= 
= 36°

Answer:
3/5
Step-by-step explanation:
odd numbers in a standard dice is : 1, 3,5.
therefore there are 3 out of 6 possibilities of it being pink rose.
Answer:
The correct answer is D. 360°
Step-by-step explanation:
The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.
Let us consider the image attached.
First of all let us consider the triangle.
As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.
Where 
are the interior angles of the triangle.
Adding the above equations:
The sum of interior angles of a triangle is always equal to 180°
Hence, proved that the sum of exterior angles is 
.
So, the correct answer is D.
