Slope of the side DA of the rectangle ABCD is $$\frac{5}{3}$$. What is the slope of the side AB?
A. $$\frac{3}{5}$$
B. $$\frac{{ - 5}}{3}$$
C. $$\frac{5}{3}$$
D. $$\frac{{ - 3}}{5}$$
Answer: Option D
Solution (By Examveda Team)
In given rectangle
Let $$\square $$ ABCD
Angle of rectangle = 90°
AB ⊥ DA
∴ Slope $$\left[ {{{\text{m}}_1} = \frac{{ - 1}}{{{{\text{m}}_2}}}} \right]$$ (when lines are perpendicular to each other)
Slope of side DA (m1) = $$\frac{5}{3}$$
Slope of side AB (m2) = $$\frac{{ - 3}}{5}$$
