How do you subtract and add mixed numbers?

oYou first need to convert from a mixed number to an improper fraction by multiplying the whole number by the denominator and adding that number to the number currently in the numerator. Then, you need to make sure they have a common denominator, and if not you need to find the greatest common denominator. Then you can add or subtract them.

∠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.
