Cartesian plane

Question

The points A(2, 3), B(5, 4), C(6, 7) forms

Moderate

A

right angled isosceles
B

acute angled isosceles
C

obtuse angled isosceles
D

Scalene

Solution

$A = (2, 3), B (5, 4), C (6, 7)$
$A B = \sqrt{9 + 1} = \sqrt{10}, B C = \sqrt{1 + 9} = \sqrt{10}, C A = \sqrt{16 + 16} = \sqrt{32}$

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

$∴ Δ A B C$ is obtuse angled triangle
