Geometry / Module 03: Proofs of Theorems Carlos draws a transversal, t, on two parallel lines AB and CD, as shown below:
B
f
C.
D
He makes the following table to prove that the alternate interior angles are equal:
Statement Justification
angle 1 = angle 5 Corresponding angles of parallel lines are congruent.
angle 1 = angle 3 ?
transitive property of equality,
angle 3 = angles angle = angle 5,
angle 1 = angle 3,
therefore angle 3 = angle 5

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
