What is true about postulates and theorems? (Select all that apply.)

• Postulates explain undefined terms and serve as a starting point for proving other statements as you go through the course.

• Theorems are statements that have been proven true using other theorems, definitions, or postulates.

• Postulates are statements that are assumed to be true.

• Theorems and postulates are only found in Geometry.
