THIS IS MULTIPLE PARTS. here are the other parts. 2) what is the sum of the measures of the angles in a triangle?

3) Angle 1 is in a triangle with angle 4 an 53° angle. What is the son of the measures of those two angles?

4) what is the measure of 1? Explain

5) find the measures of 2. Explain how you found its measure

6) what is the measure of 3? Explain

I’m sorry it’s so long but If anyone could help or explain It would help so much! :)

∠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.
