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

= \frac{360}{\text{Number of sides in a regular polygon}}

= \frac{360}{10}

= 36°

Answer:

a) (+) × (?) = (+)

(?) = (+)

b) (-) × (+) = ?

? = (-)

c) (?) × (-) = ?

? is undefined

Step-by-step explanation:

a) (+) × (?) = (+)

From the given equation in the question, by dividing both side of the equation by (+), we have;

((+) × (?))/(+) = (+)/(+)

(?) = (+)/(+) = (+)

Therefore, we have;

(+) × (+) = (+)

(?) = (+)

b) (-) × (+) = ?

From the given equation in the question we apply the operation rules as follows;

(-) × (-) = (+)

(-) × (+) = (-)

Therefore;

(-) × (+) = ? = (-)

? = (-)

c) (?) × (-) = ?

From the rules of multiplication, we have;

(-) × (-) = (+)

(+) × (-) = (-)

Therefore, when (?) = (-), ? = +, from which we have;

(?) ≠ ?, which is an error

Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign

Therefore, the equation, (?) × (-) = ?, is undefined.
