PLEASE HELP How do the definitions, properties, and postulates you've learned about line segments, parallel lines, and angles help to define the shapes of polygons?

So it helps because it proves the basic things that shape has.

Step-by-step explanation:

So for example,

A Triangle: 3 sides,3 interior angles that add up to 180, Each exterior angle is 120 degrees maximum.

A Parallelogram: Has two sets of parallel lines and consecutive angles are supplementary

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
