10th Maths Book Back Answers/Solutions:
TN Samacheer Kalvi 10th Maths Chapter 5 Book Back Exercise given below. The 10th Maths Book Back Solutions Guide is uploaded below:
Exercise 5.2 Coordinate Geometry
1.What is the slope of a line whose inclination with the positive direction of x -axis is
(i) θ = 90°
m = tan θ = tan 90° = ∝ (undefined)
(ii) m = tan θ = tan 0° = 0
2.What is the inclination of a line whose slope is (i) 0
(i) Slope = 0
tan θ = 0
tan 0 = 0
∴ θ = 0°
(ii) Slope = 1
tan θ = 1
tan 45° = 1
∴ θ = 45°
angle of inclination is 45°
3.Find the slope of a line joining the points
(i) (5, 5–√)) with origin
(ii) (sin θ, -cos θ) and (-sin θ, cos θ)
(i) (5, 5–√)) with origin (0, 0)
4. What is the slope of a line perpendicular to the line joining A(5, 1) and P where P is the mid-point of the segment joining (4, 2) and (-6,4).
P is the midpoint of the segment joining (4, 2) and (-6, 4)
The slope of AB = Slope of BC
∴ The points A, B, and C lie on the same line.
∴ They are collinear.
9.Show that the given points form a right angled triangle and check whether they satisfies pythagoras theorem
(i) A(1, -4), B(2, -3) and C(4, -7)
(ii) L(0, 5), M(9, 12) and N(3, 14)
∴ The given points form a parallelogram.
∴ One pair of opposite sides are parallel.
∴ ABCD is a trapezium.
In a parallelogram diagonals bisect each other. Opposite sides are parallel as their slopes are equal the mid points of the diagonals are the same.
∴ Mid points of the sides of a quadrilateral form a parallelogram.
