Given: e ll f and g is transversal prove: ∠1 ≅ ∠8

given that e ii f and g is a transversal, we know that ∠4 ≅ ∠5 by the alternate interior angles theorem. we also know that ∠1 ≅ ∠4 and ∠5 ≅ ∠8 by the therefor, ∠1 ≅ ∠8 by the substitution property.

a. corresponding angles theorem

b. alternate interior angles theorem

c. vertical angles theorem

d. alternate exterior angles theorem

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
