Determine if the statement is always, sometimes or never true.

an equilateral triangle is a regular polygon.

a. always
b. sometimes
c. never

Equilateral triangle is always a regular polygon

Step-by-step explanation:

We have to tell an equilateral triangle is a regular polygon.

Regular polygon is a polygon which has all angles and all sides are equal.

Equilateral triangle is a triangle with all three angles equal to 60° and all three sides equal.

Hence equilateral triangle is always a regular polygon

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
