Yesterday in class students worked with a Geogebra activity to explore the angles created when parallel lines are crossed by a transverse line. Today in class students used what they have learned to figure out the measures of many angles in a given figure.
Answers to angle measurements: Bold side line CF parallel to line BG m<1 = 60 m<8 = 30 m<2 = 120 m<9 = 60 m<3 = 60 m<10 = 90 m<4 = 120 m<11 = 30 m<5 = 150 m<12 = 60 m<6 = 30 m<13 = 90 m<7 = 150 m<14 = 30 Lighter side line A parallel to line B m<1 = 110 m<13 = 90 m<25 = 145 m<2 = 70 m<14 = 90 m<26 = 35 m<3 = 55 m<15 = 90 m<4 = 55 m<16 = 90 m<5 = 70 m<17 = 90 m<6 = 20 m<18 = 55 m<7 = 160 m<19 = 70 m<8 = 20 m<20 = 55 m<9 = 70 m<21 = 55 m<10 = 90 m<22 = 70 m<11 = 20 m<23 = 55 m<12 = 70 m<24 = 35
