A rectangle is shown. A line is drawn from a corner to the opposite corner to form 2 triangles. The area of a rectangle in 24 square units. A diagonal drawn from one corner to another divides the rectangle into two right triangles. What is the area of the shaded triangle? 2 times 24 square units 1 times 24 square units One-half times 24 square units One-fourth times 24 square units

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.
