= √[36 + 16] = √52

Answer: √52 units

Q. Find the midpoint of the line joining (2, 3) and (6, 7).

Solution: Midpoint = ((2 + 6)/2, (3 + 7)/2)

= (8/2, 10/2)

= (4, 5)

Answer: (4, 5)

Q. Find the midpoint of the line joining (−4, −2) and (6, 4).

Solution: Midpoint = ((−4 + 6)/2, (−2 + 4)/2)

= (2/2, 2/2) = (1, 1)

Answer: (1, 1)

Q. Find the coordinates of the point dividing the line joining (2, 4) and (6, 8) in the ratio 1:1.

Solution: Using section formula:

= ((1×6 + 1×2)/2, (1×8 + 1×4)/2)

= (8/2, 12/2) = (4, 6)

Answer: (4, 6)

Q. Find the coordinates of the point dividing the line joining (3, −2) and (−5, 4) in the ratio 3:1.

Solution:

= ((3×(−5) + 1×3)/4, (3×4 + 1×(−2))/4)

= (−15 + 3)/4, (12 − 2)/4 = (−12/4, 10/4)

= (−3, 2.5)

Answer: (−3, 2.5)

Q. Find the area of triangle with vertices A(1, 1), B(4, 4), and C(1, 5).

Solution:

Area = 1/2 |1(4−5) + 4(5−1) + 1(1−4)|

= 1/2 |−1 + 16 −3| = 1/2 × 12

Answer: 6 sq units

Q. Find the area of triangle with vertices (0, 0), (4, 0), (4, 3).

Solution:

Area = 1/2 |0(0−3) + 4(3−0) + 4(0−0)|

= 1/2 |0 + 12 + 0| = 1/2 × 12

Answer: 6 sq units

Q. If the distance between points (x, 5) and (1, 1) is 5, find x.

Solution:

√[(x−1)² + 16] = 5 → (x−1)² = 9 → x − 1 = ±3

⇒ x = 4 or x = −2

Answer: x = 4 or −2

Q. Find the point on x-axis equidistant from (2, 3) and (−4, 5).

Solution: Let point be (x, 0).

Distance from (2, 3): √[(x−2)² + 9]

Distance from (−4, 5): √[(x+4)² + 25]

Squaring both: (x−2)² + 9 = (x+4)² + 25

= x² − 4x + 4 + 9 = x² + 8x + 16 + 25

= −12x = 28 → x = −7/3

Answer: (−7/3, 0)

Q. Find the length of diagonal of rectangle with vertices (1, 2), (1, 6), (5, 6), (5, 2).

Solution:

Diagonal = √[(5−1)² + (6−2)²] = √[16 + 16] = √32

Answer: √32 units

Q. Show that points (1, 2), (3, 4), and (5, 6) lie on a straight line.

Solution:

Slope of AB = (4−2)/(3−1) = 1

Slope of BC = (6−4)/(5−3) = 1

Slopes are equal ⇒ points are collinear

Answer: Yes, collinear

Q. Find the centroid of triangle with vertices (1, 2), (3, 4), (5, 0).

Solution:

Centroid = ((1+3+5)/3, (2+4+0)/3) = (9/3, 6/3) = (3, 2)

Answer: (3, 2)

Q. Find the diagonal of a square with side 5 units.

Solution: Diagonal = √2 × side

= √2 × 5 = 5√2

Answer: 5√2 units

Q. Find area of triangle with vertices (2, 3), (4, 7), (6, 3).

Solution: Area = 1/2 |2(7−3) + 4(3−3) + 6(3−7)|

= 1/2 |8 + 0 −24| = 1/2 × 16

Answer: 8 sq units

Q. Prove that triangle with vertices (0, 0), (2, 2), (4, 0) is isosceles.

Solution: AB = BC = √[(2−0)² + (2−0)²] = √8

AC = √[(4−0)²] = 4

AB = BC ⇒ triangle is isosceles

Answer: Yes, it is isosceles

Q. Find the coordinates of a point on the line joining (3, 4) and (6, 10) whose x-coordinate is 3.

Solution: Given x = 3, which is the x-coordinate of the first point.

So, the point is simply: (3, 4)

Answer: (3, 4)
