How do defined terms and undefined terms relate to each other? correct answers Undefined terms will be used as a foundational element in defining other "defined" terms. The undefined terms include point, line, and plane. The defined terms discussed so far include angle, circle, perpendicular line, parallel line, and line segment. What is the difference between a postulate and a theorem? correct answers A postulate is considered a known fact. Undefined terms, defined terms, and postulates wi...

Gradient y2-y1/x2-x1 Length of a line sqrt((x2-x1)^2+(y2-y1)^2) Midpoint (x1+x2/2, y1+y2/2) How do you know if two lines are perpendicular? When you multiply the gradients together they should equal -1. The general rule is perpendicular = -1/m. Or you could use Pythagoras to show there is a right angle How do you know if two lines are parallel? The gradients should be the same What should you always remember when finding the square roots? The answer could...
