Question

L and M are parallel lines, which have been intersected by the parallel lines P and Q. Show ∆ABC is congruent to ∆CDA.​

Answer 1

Answer:

See that ABC are making a triangle , CDA are also making a triangle from each other

Answer 2

$\huge\pink{\mid{\underline{\overline{\tt Answer:-}}\mid}}$

GIVEN THAT,

l and m are parallel lines.

In ∆ABC and ∆CDA,

AD=BC (since l and m are parallel lines)

Angle BCA= Angle CAD (since these angles are alternate interior angles)

AC= AC (common side)

THEREFORE, ∆ABC=∆CDA (by SAS congruence).
