4. Consider the following graph. Part A: Plot two points to form a square in the above graph. Label the points R and
S. A square is a quadrilateral with all four sides of the same length. After
plotting the points, trace the square by connecting the points.
Part B: To find the perimeter of a polygon, take the sum of the length of each side.
What is the perimeter of the square that you created in Part A Round your
answer to two decimal places.

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.
