Question 2 on plato geometry 2 70 points

To explore relationships among the sides and angles, move points B and C so that m∠CFB equals 45°, 50°, 60°, and 75°, successively. Measure the values listed in the tables to two decimal places. (It’s acceptable if the radius of the circle changes as you move B and C.)

Answer 1

m∠CFB m∠CAB m∠EAD m ∠CAB + m∠EAD

45° 19.93° 70.07° 90°

50° 29.91° 70.09° 100°

60° 49.92° 70.08° 120°

75° 79.92° 70.08° 150°

m∠CFB BF CF DF EF BF + DF CF + EF BF × DF CF × EF

45° 2.69 2.74 9.09 8.91 11.78 11.65 24.45 24.41

50° 3.7 3.63 8.07 8.23 11.77 11.86 29.86 29.87

60° 5.35 4.72 6.42 7.28 11.77 12.00 34.35 34.36

75° 7.3 5 4.47 6.52 11.77 11.52 32.63 32.6
