  1. Drawing Free-Body Diagrams . Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free -body diagram is a special example of the vector diagrams; these diagrams will be used throughout your study of physics. The size of the arrow in a free -body diagram is ...

  2. Aim: I can determine the measure of Complementary, Supplementary, & Vertical Angles. 1) What is the supplement of a 42º angle? _____ 2) What is the complement of a 83º angle? _____ 3) An angle measures 57º, what does a angle vertical to it measure? _____ 4) If m < ABD = 35º, what is the m < CBD? 5) If angle 3 measures 122º, what does angle ...

  4. Worksheet #1 Free Body or Force diagrams Drawing Free-Body Diagrams Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams; these diagrams will be used throughout your study of physics.

  5. Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other. Let's learn about the vertical angles theorem and its proof in detail.

  6. Whenever two lines intersect, two pairs of vertical angles are formed. We are allowed to assume vertical angles from the diagram. Vertical Angles Theorem: Vertical angles are congruent.

  7. Free-Body Diagrams. In each of the following situations, represent the object with a particle. Sketch all the forces acting upon the object, making the length of each vector represent the magnitude of the force. Object lies motionless.
