Which triangles are similar?
justify your reasoning

Triangles OPQ and NPR are similar by AA Similarity Postulate

Step-by-step explanation:

we know that

In this problem

NR is parallel to OQ

therefore

Triangles OPQ and NPR are similar by AA Similarity Postulate (the three internal angles are congruent)

because

<RNP=<QOP -----> by corresponding angles

<NRP=<OQP ----> by corresponding angles

<NPR=<OPQ

Remember that

If two triangle are similar, then the ratio of its corresponding sides is equal

Verify

substitute the values

-----> is true

therefore

The triangles OPQ and NPR are similar

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 : )

c) yes, because of asa or aas
