Q69.The points (0, 38 ), (1, 3) and (82, 30) (1) form an obtuse angled triangle (2) form an acute angled triangle (3) lie on a straight line (4) form a right angled triangle
What This Question Tests
This question requires checking the collinearity of three points using their slopes; if not collinear, further analysis (e.g., using distance formula or dot product) would classify the triangle type.
Concepts Tested
Formulas Used
m = (y2-y1)/(x2-x1)
Distance = √((x2-x1)² + (y2-y1)² )
