Solution

The correct option is C Right angled triangle

Suppose,
$Δ A B C$ is a right angled triangle.
We can see that two sides $B C$ and $A C$ are perpendicular to each other.

An altitude is a perpendicular line drawn from the vertex to the opposite side of the triangle.

$∴$ Here, side BC is also an altitude from B to the side AC and also side AC is an altitude from A to side BC.
