• Aug 02, 2013 · The hypothesis of the conditional statement is not true, so we do not know if the conclusion is true. 3. Given: If the sum of the measures of two angles is 180, then the angles are supplementary. Zl and Z2 are a linear pair. Conclusion: Zl and Z 2 are supplementary. If Zl and /-2 are a linear pair, then the sum of their measures is 180.

• If two angles are a linear pair, then they are supplementary. More Examples: Rewrite as conditional statements All 90° angles are right angles. When n = 9, n² = 81. Tourists at the Alamo are in Texas.
3) If two angles form a linear pair, then the angles are supplementary. Hypothesis: Conclusion: Directions: Write a conditional statement. Congruent angles have equal measures. 7) Alternate exterior angles are congruent when two lines are paral{el and cut by a transversal. 2) If a figure has 8 sides, then it is an octagon. Hypothesis: Conclusion: 1-4 Pairs of Angles Check It Out! Example 1a 5 and 6 Tell whether the angles are only adjacent, adjacent and form a linear pair, or not adjacent. 5 and 6 are adjacent angles. Their noncommon sides, EA and ED, are opposite rays, so 5 and 6 also form a linear pair.
Sep 02, 2013 · Example If it is raining, then there are clouds in the sky. If the car is a Mustang, then it is a Ford. Writing Conditional Statements All birds have feathers. Two angles are supplementary if they are a linear pair. More Examples All 90° angles are right angles. When n = 9, n² = 81. Tourists at the Alamo are in Texas. A pair of supplementary angles sum to 180°. A linear pair of angles are both supplementary and adjacent. Vertical angles share a vertex and are formed by extending each ray though the vertex. The letter X provides some good examples. The angle opening upward and the angle opening downward are vertical angles as are the pair opening left and right. Vertical angles have an easily proved property given below.
” Use Althea’s method and tracing paper to determine if the following angle pairs are congruent or supplementary. Be sure to state whether the pair of angles created after the translation is a vertical pair or forms a straight angle. Be ready to justify your conclusions for the class. b = 48. Supplementary. Congruent. Supplementary When a transversal cuts two parallel lines, we have the following interesting relationships: Each pair of corresponding angles are equal. ∠1 = ∠5, ∠3 = ∠7, ∠2 = ∠6, ∠4 = ∠8 Each pair of alternate interior angles are equal. ∠3 = ∠6, ∠4 = ∠5 Each pair of interior angles on the same side of transversal are supplementary. ∠3 + ∠5 = 180°, ∠4 + ∠6 = 180°
