Question

Step 1: m∠m + m∠n + m∠p = 180 degrees (sum of angles of a triangle)
Step 2: m∠p + m∠o = 180 degrees (adjacent supplementary angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p

In which step did the student first make a mistake and how can it be corrected?

Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)

Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)

Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)

Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Answer 3

please you have to provide the corresponding drawing

Answer 4

interior angles are:
m, n, and o
so we have:
m<m+ m<n + m<o= 180

Answer 5

OKAY

Answer 6

so its step one A (:

Answer 7

correct!
