Please help me ;-; i will mark brainliest Which of the following statements must be true about this diagram ?
A. m ∠ 3 is greater than m ∠ 2
B. m ∠ 1 + m ∠ 2 = m ∠ 4
C. m ∠ 1+ m ∠ 2 = m ∠ 3
D. m ∠ 2 + m ∠ 3 = m ∠ 4
E. m ∠ 4 is greater than m ∠ 1
F. m ∠ 4 is greater than m ∠ 2

B. m∠4 is greater than m∠2 C. m∠4 is greater than m∠1   F. The degree measure of m∠4 equals the sum of the degree measures of m∠1 and m∠2

Step-by-step explanation:

So, these options are true: B. m∠4 is greater than m∠2 {by the exterior angle theorem] C. m∠4 is greater than m∠1  {by the exterior angle theorem]
