Question

From point I (incenter), a perpendicular IP is drawn onto side BC. What does the length IP represent?

Options

• The diameter of the incircle

• The height of the triangle

• The inradius of the incircle

• The semi-perimeter of the triangle

Answer 1

The inradius of the incircle

Explanation:

The perpendicular distance from the incenter to any side of the triangle equals the radius of the in-circle, called the inradius (r).
