Armando is marking off a grass soccer field for a soccer game. He has a long tape measure and a chalk for lining the field. Armando wants to make sure that the corners of the field are right angles. How can he use the tape measure to ensure that he makes right angles?

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

the discriminant is 64 + 4*1*12 = 112

this is prime.

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.
