1. If ∠D ≅ ∠E, then
2. Definition of Complementary Angles: If m∠1 + m∠2 = 90°, then
3. Definition of Supplementary Angles: If ∠P and ∠Q are supplementary angles, then
4. Definition of a Right Angle: If m∠ JKL = 90°, then
5. Vertical Angles Theorem: If ∠3 and ∠4 are vertical angles, then
6. Complement Theorem: If ∠S and ∠T form a right angle, then
7. Supplement Theorem: If ∠X and ∠Y form a linear pair, then
8. Congruent Complements Theorem: If ∠1 is complementary to ∠2 and ∠2 is complementary to ∠4, then
9. Congruent Complements Theorem: If ∠J is supplementary to ∠K and ∠J is supplementary to ∠L, then

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 : )
