Athree sided regular polygon is called equilateral. true or false

True.

Step-by-step explanation:

Since, A regular polygon is a polygon that is equi-angular (all angles are equal in measure) and equilateral (all sides have the same length).

Since, If a three sided polygon is a regular polygon.

⇒ The measurements of its all angles are same.

Therefore, measurement of its all angles is 60° ( because 180°/3)

⇒Also, It has the same edges.

Since, It is following the conditions of equilateral triangle.

Therefore, It must be an equilateral triangle.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
