Part II: Patterns & Observations
Part III: Rule
|
Recall your knowledge of supplementary and complementary angles. What relationships do you notice between the sums of the measures of the adjacent angles when “Vertical Angles” is shown on the screen? Include the terms “adjacent angles” and “linear pair” in your description. If you’re not sure what these terms mean, feel free to look them up in the Notability guided notes. Your answer should be 3-4 complete sentences. |
Part V: Rule
A theorem is a rule written in "if, then" form that can be proven. |
Use your explanation from question 2 in part II to write a theorem (rule) about the measurements of linear pairs. Answer this part independently without collaborating. If _______________________________________________________________ ______________________________________________________________, then, __________________________________________________________ _______________________________________________________________
|
Discuss your theorem with your partner. Then, we will share answers as a group. In the space below, write a revised theorem: If _______________________________________________________________ ______________________________________________________________, then, ___________________________________________________________ _______________________________________________________________ |
Part VI: Solving a Problem (Test & Check)
Use the rule you created in question 3 of part III to solve problems. |
While creating stairs for a deck, it is important that the support beam on the top of the stairs has the same angle with the rail as the support beam on the bottom of the stairs. The picture below shows the measure of the angle underneath the rail to the right of the support beam. What are the measures of the other three angles around the rail? Show your work. |
Use your answer from question 2 and the image below to write equations that can be used to solve for x and y. Remember, equations must have equal signs. Then, solve the equation. Remember to show all of your work! Equation to find x: Solution: Equation to find y: Solution: |
