The statements that are true for the image below are:
A. m∠B = m∠C + 33° (exterior angle theorem)
C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)
D. m∠D + m∠B + 128° = 360° (sum of exterior angles)
G. m∠D = 180° - 33° (angles on a straight line)
What is the Triangle Sum Theorem?
The triangle sum theorem states that, all the interior angles of a triangle will give a sum of 180°.
Also, angles on a straight line sum up to 180°.
Sum of all exterior angles of any polygon = 360°.
Therefore, the statements that are true for the image below are:
A. m∠B = m∠C + 33° (exterior angle theorem)
C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)
D. m∠D + m∠B + 128° = 360° (sum of exterior angles)
G. m∠D = 180° - 33° (angles on a straight line)
