How can you solve real-world problems that involve angle relationships in parallel lines and triangles?

PLEASE ANSWER

Well, lets say your a construction worker, you'll need you measure each angle to make sure there perfect and fit the exact way for your material, and If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally

Step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
