• B. an acute angled triangle
• C. a right angled triangle
• D. None of these

Answer 1

The correct option is D None of these

A] vertices of $△$ are $A(0,\frac{8}{3}),B(1,3)$ & $C(82,30)$

$m_1=$ slope of AB = $\frac{3-\frac{8}{3}}{1-0}=\frac{1}{3}$

$m_2=$ slope of BC $=\frac{30-3}{82-1}=\frac{1}{3}$

as $m_1=m_2$

$\therefore A,B,C$ are collinear & will not form any

$△$
