Open perpendicular lines again. You'll use the same modern technology, but this time you’ll apply an old-fashioned approach to construct a perpendicular bisector: Create a circle centered at A with a radius greater than half the length of .
Create another circle centered at B with the same radius.
Label the points where the circles intersect E and F.
Draw a line through E and F.
Mark the point where intersects as G.
Measure the lengths of and .
Measure the angle at which intersects .

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
