Determine the measures of the angles marked with letters.
1. Answer: [tex]\bold\blue{\tt{m∠m=120°}}[/tex]
Proof: Alternate Interior Angles Theorem
2. Answer: [tex]\bold\blue{\tt{m∠n=70°}}[/tex]
Proof: Alternate Exterior Angles Theorem
3. Answer: [tex]\bold\blue{\tt{m∠r=105°}}[/tex], [tex]\bold\blue{\tt{m∠s=75°}}[/tex]
Proof:
For ∠r, Linear Pair Theorem and Corresponding Angles Theorem
For ∠s, Vertical Angles Theorem
