There are actually 2 variations in this case.

> First case: the number of sides is an odd number

<span>                The number of lines of symmetry is simply equal to number of sides</span>

 

> Second case: the number of sides is an even number

<span>                The number of lines of symmetry is equal to twice the number of sides</span>

X sides because every regular polygon has the same amount of lines of symmetry as the amount of sides.

Can someone explain this? :)
Alchen [17]

I'll do part (a) to get you started.

The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.

We also see that b = 123 as well since a = b (they are vertical angles).

Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.

c+123 = 180

c = 180-123

c = 57

-------------------------

To summarize, we have these three angles

a = 123

b = 123

c = 57
