Paul rotates ABCDE by 90° clockwise to produce FGHIJ. In ABCDE, m∠A=105°, m∠B=120°, m∠C=90°, m∠D=120°, and m∠E=105°.
Since Paul rotated ABCDE by 90° clockwise to produce FGHIJ, the order of the letters remains the same but the angles have changed. To determine the angles in FGHIJ, we need to consider that a 90° clockwise rotation will result in a reflection across the y-axis followed by a reflection across the x-axis.
m∠F = m∠A = 105°
m∠G = m∠B - 90° = 30°
m∠H = m∠C = 90°
m∠I = m∠D - 90° = 30°
m∠J = m∠E = 105°
Therefore, in FGHIJ, m∠F=105°, m∠G=30°, m∠H=90°, m∠I=30°, and m∠J=105°.
