Conjectures are simply opinions from a given information.
The conjecture that can be formed is: C. when a pair of parallel lines is intersected by a third line, the corresponding angles are congruent
From the three diagrams, we can see that:
- [tex]\mathbf{30^o = 30^o}[/tex]
- [tex]\mathbf{35^o = 35^o}[/tex]
- [tex]\mathbf{50^o = 50^o}[/tex]
From the figures above, we have the following observations
- The angles are congruent
- The angles are corresponding
- The congruence of the angles is based on parallel lines, intersected by a third line (i.e. the transversal)
Hence, the conjecture that can be formed is: option (c)
