Atriangle is equilateral if, and only if, it has three congruent angles.
based on this statement, which of the following is true?
a triangle has three congruent angles, therefore the triangle is equilateral.
a triangle is equilateral, therefore the triangle has no congruent angles.
a triangle is equilateral, therefore it has exactly two congruent angles.
a triangle has three congruent sides, therefore the triangle is isosceles.

Step-by-step explanation:

a triangle has three congruent sides there for the triangle is equilateral

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
