In the figure, transversal m intersects parallel lines į and k. Part B Based on the given figure, a student wrote these statements to prove that if a transversal intersects two parallel lines, alternate interior angles have equal measure. Step 1: m25 + m26 = 180°;m23+m22%= 180° Step 2: m5 + m26= m3 + mZ2 Step 3: mZ6 = m Z 2 Step 4: ? Step 5: m2 = mZ2 Step 6: mZ5 = m23 1 4/3 8 7. What statement is missing in Step 4? am25+m26 = m Z 3 + m Z4 (b) m25+m26=mZ1+ m24 ©m25+m22 = m Z 3 + m2 Om 5+mZ8 = m Z 3 + m2

ZABD and ZDBC form a linear pair, and ZABD and ZCBE are vertical angles. If MLABD = 2(5z – 11), m/DBC=2¤+10, and m/CBE==y+36, select all the statements that are true. 16 y = 153 O m/CBE = 42 O MLABD= 138 O MLABE = 138 O ZDBC and ZABE are vertical angles. https://ola3.performancematters.com/ola/ola.jsp?dlientCodesfiduvale Pause P Type here to search Esc F3 F10 23 & 1 3 4 7 Q R T Y Tab CapsLk S F G J K Shift V M Ctri Fn Alt טא CU O O
