Q92. Show that points (1,5), (2,3) and (−2,−11) are collinear.

Difficulty: Easy-Medium · Topic: Distance Formula

Solution

Area = ½|1(3−(−11))+2(−11−5)+(−2)(5−3)| = ½|14−32−4| = ½|−22| = 11 ≠ 0.

Actually they are NOT collinear. Let me verify: slope(1→2) = (3−5)/(2−1) = −2. slope(2→−2) = (−11−3)/(−2−2) = −14/−4 = 3.5 ≠ −2. Not collinear.

Let's use correct collinear points: (1,−1), (2,1), (4,5). Area = ½|1(1−5)+2(5+1)+4(−1−1)| = ½|−4+12−8| = 0. Collinear ✓.

Q377. If (1,2), (4,y), (x,6) and (3,5) are vertices of a parallelogram taken in order, find x and y.

Difficulty: Medium-Hard · Topic: Distance Formula

Solution

Diagonals of parallelogram bisect each other. Midpoint of (1,2)&(x,6) = midpoint of (4,y)&(3,5).

(1+x)/2 = 7/2 → x = 6. (2+6)/2 = (y+5)/2 → y = 3.

Q378. If the area of the triangle formed by (x,2x), (−2,6) and (3,1) is 5 sq units, find x.

Difficulty: Medium-Hard · Topic: Area of a Triangle

Solution

½|x(6−1)+(−2)(1−2x)+3(2x−6)| = 5.

½|5x−2+4x+6x−18| = 5 → ½|15x−20| = 5 → |15x−20| = 10.

15x−20 = 10 → x = 2. Or 15x−20 = −10 → x = 2/3.

Q379. Show that the points (a,a), (−a,−a) and (−a√3, a√3) form an equilateral triangle.

Difficulty: Medium-Hard · Topic: Distance Formula

Solution

AB = √[(−2a)²+(−2a)²] = √(8a²) = 2a√2.

BC = √[(−a√3+a)²+(a√3+a)²] = √[a²(√3−1)²+a²(√3+1)²] = a√[(4−2√3)+(4+2√3)] = a√8 = 2a√2.

AC = √[(−a√3−a)²+(a√3−a)²] = a√[(√3+1)²+(√3−1)²] = a√8 = 2a√2.

AB = BC = AC → equilateral.
