How should the following statement be written in if - then form?

the sum of the measures of the angles of a triangle is 180 degrees.

If a triangle exists, then the sum of the measures of the angles is 180 degrees.

Step-by-step explanation:

Here the hypothesis is "a triangle" and the conclusion is "the sum of the measures of the angles of is 180 degrees."

If-then statement or a conditional statement is denoted as p → q. or it is written as if p then q, where p is the hypothesis and q is the conclusion.

Therefore, the if-then statement for the given statement is If a triangle exists, then the sum of the measures of the angles is 180 degrees.

to complete this square you have to rotate about the origin 270 degrees clockwise.
