Given:
- \( jk \parallel lm \)
- \( jk = lm \)
- \( l \) is the midpoint of \( jn \)

Prove:
- \(\triangle ajl \cong \triangle alm\)

Statements and Reasons:
1. \( jk \parallel lm \) and \( jk = lm \) - Given
2. \( l \) is the midpoint of \( jn \) - Given
3. \( jl = ln \) - Definition of midpoint
4. \(\angle ajl = \angle alm\) - Corresponding Angles Theorem
5. \(\triangle ajl \cong \triangle alm\) - SAS (Side-Angle-Side) Congruence Postulate

Answer :

Final answer:

The given statement ajlk = alnm can be proved using the corresponding angles theorem and the fact that l is the midpoint of jn. By applying these properties and using the transitive property of equality, we can conclude that the triangles ∆ajk and ∆alm are congruent, which implies that ajlk = alnm.

Explanation:

To prove that ajlk = alnm, we can use the corresponding angles theorem and the fact that l is the midpoint of jn.

Given: jk || lm, jk = lm, l is the midpoint of jn

Statement 1: jk || lm (Given)

Statement 2: jk = lm (Given)

Statement 3: l is the midpoint of jn (Given)

Statement 4: ∠ajk = ∠alm (Corresponding angles theorem)

Statement 5: ∠jkl = ∠lkm (Corresponding angles theorem)

Statement 6: ∠ajk = ∠jkl (Vertical angles are congruent)

Statement 7: ∠alm = ∠lkm (Vertical angles are congruent)

Statement 8: ∠ajk = ∠jkl = ∠alm = ∠lkm (Transitive property of equality)

Statement 9: ∆ajk ≅ ∆alm (Angle-side-angle congruence)

Statement 10: ajlk = alnm (Corresponding parts of congruent triangles are congruent)

Therefore, we have proved that ajlk = alnm using the given information and the corresponding angles theorem.
