Cartesian plane

Question

The points (3, 4), (2, 5), (3, 7) forms

Easy

A

acute angled scalene
B

obtuse angled scalene
C

right angled scalene
D

Equilateral

Solution

$A (3, 4), B (2, 5), C (3, 7)$
$A B = \sqrt{1 + 1} = \sqrt{2}$

$B C = \sqrt{1 + 4} = \sqrt{5}$

$C A = \sqrt{0 + 9} = 3$

$A B^{2} + B C^{2} < A C^{2}$

$∴ Δ A B C$ is obtuse angled scalene
