The congruence theorem that can be used to prove triangle lon is congruent to triangle lmn is

 SSS

Step-by-step explanation:

In the given picture we have two triangles and in which

Thus by SSS congruence criteria we have,

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

if you need just tell me and i will come to the rescue.
