### Access answers to RD Sharma Solutions Class 11 Maths Chapter 23 Exercise 23.14- Important Question with Answers

**1. Find the values of α so that the point P(α ^{2}, α) lies inside or on the triangle formed by the lines x – 5y + 6 = 0, x – 3y + 2 = 0 and x – 2y – 3 = 0.**

**Solution:**

Given:

x – 5y + 6 = 0, x – 3y + 2 = 0 and x – 2y – 3 = 0 forming a triangle and point P(α^{2}, α) lies inside or on the triangle

Let ABC be the triangle of sides AB, BC and CA whose equations are x − 5y + 6 = 0, x − 3y + 2 = 0 and x − 2y − 3 = 0, respectively.

On solving the equations, we get A (9, 3), B (4, 2), and C (13, 5) as the coordinates of the vertices.

It is given that point P (α^{2}, α) lies either inside or on the triangle. The three conditions are given below.

(i) A and P must lie on the same side of BC.

(ii) B and P must lie on the same side of AC.

(iii) C and P must lie on the same side of AB.

If A and P lie on the same side of BC, then

(9 – 9 + 2)(α^{2} – 3α + 2) ≥0

(α – 2)(α – 1) ≥ 0

α ∈ (- ∞, 1 ] ∪ [ 2, ∞) … (1)

If B and P lie on the same side of AC, then

(4 – 4 – 3) (α^{2} – 2α – 3) ≥ 0

(α – 3)(α + 1) ≤ 0

α ∈ [- 1, 3] … (2)

If C and P lie on the same side of AB, then

(13 – 25 + 6)(α^{2} – 5α + 6) ≥0

(α – 3)(α – 2) ≤ 0

α ∈ [ 2, 3] … (3)

From equations (1), (2), and (3), we get

α∈ [2, 3]

∴ α∈ [2, 3]

**2. Find the values of the parameter a so that the point (a, 2) is an interior point of the triangle formed by the lines x + y – 4 = 0, 3x – 7y – 8 = 0, and 4x – y – 31 = 0.**

**Solutions:**

**3. Determine whether the point (-3, 2) lies inside or outside the triangle whose sides are given by the equations x + y – 4 = 0, 3x – 7y + 8 = 0, 4x – y – 31 = 0.**
