  1. Parallel Lines & Corresponding Angles Name:______________ Date:______ Do Now: Do Now Too:

  2. Notes for today: AB is called a ___________________. A ____________________ intersects two or more other lines Shade the interior of  AOD & GEO. These angles are called ______________________________ There are three other pairs of ___________________________ They are __________________&____________________, __________________&____________________ and __________________&____________________ A C O D F E G B Answer each e. 5 and ________ are vertical angles f. 7 and ________ and 7 and ________ are both linear pairs g. If m5 = 3m and m6 = 6m, find m7 & m8. Explain your reasoning

  3. Copy the Corresponding Angle Postulate Solve the following problem: A Here AB is intersecting parallel lines. We know because _____________________________________________ and we write that as ___________________________ When a transversal intersects parallel lines then the corresponding angles are __________________ Given mDOE = 5x + 15& m  GEB = 2x + 20, find the mBEG, mFEO and m GEO. Explain your reasoning. C O D F E G B

  4. Alternate Angles & Parallel Lines Name:______________ Date:_____ a. Highlight BHJ & PJH. These are called alternate interior angles. List the other pair of alternate interior angles. b. Label the figure so NB||PD Explain why given NB||PD, mBHJ = mPJH Alternate Interior Angle Theorem: c. If given mFHB = 128, find and list each other angle and its measure. B F H D N J L P

  5. a. Highlight 3 & 5 These are called Same Side Interior angles. List the other pair of Same Side Interior angles. b. Label the graph to show l|| m. Explain why given l ||m, m3 + m5 = 180 . 2 1 4 3 l 6 5 8 7 m Same Side Interior Angles Theorem: c. If given m5 = 112, find and list each other angle and its measure

  6. S a. Highlight UVS & ZWX. These are called alternate exterior angles. List the other pair of alternate exterior angles. b. Label the graph to show SY ||TZ. Explain why given SY||TZ, mUVS = mZWX . U V Y T W Z X Alternate Exterior Angle Theorem: c. If given mYVW = 72, find and list each other angle and its measure
