Perpendicular sides are one of the basis of mathematics. Perpendicular sides are either in a vertical direction or in the upright direction. Also this perpendicular sides are present
in a right angle manner. Perpendicular sides are also suitable for triangle, rectangular, square, **parallelogram** etc. All the shapes mentioned are having the perpendicular sides. Lets we study the perpendicular sides for triangle.

**Example problem 1: **Solve the given equation having y +4x = 20. Find the slope for the given equation which is perpendicular to the given line

**Solution:**

**Step 1: **Write the given equation**. **Therefore, y + 4x = 20

**Step 2:** For finding the slope in a given line, we have to change the given equation into the intercept form.

**Step 3:** The general formula for the slope intercept form is y = mx = c

y = 4x + 20

** Step 4:** The slope of the given line is m =4, Therefore, we get,

4m = 1, where m = slope of the perpendicular line

** Step 5: **Therefore, the slope for the given line is m = `(1)/(4)` ** .**

This is the required solution for the above problem.** **

**Example problem 2: **Solve the given equation having y +6x = 30. Find the slope for the given equation which is perpendicular to the given line

**Solution:**

**Step 1: **Write the given equation**. **Therefore, y + 6x = 30

**Step 2:** For finding the slope in a given line, we have to change the given equation into the intercept form.

**Step 3:** The general formula for the slope intercept form is y = mx = c

y = 6x + 30

** Step 4:** The slope of the given line is m =6, Therefore, we get,

6m = 1, where m = slope of the perpendicular line

** Step 5: **Therefore, the slope for the given line is m = `(1)/(6)` ** .**

This is the required solution for the above problem.** **
