What is the relationship between the inradius and the area of a triangle?
The area of a triangle can be calculated using the formula: Area = r * s, where r is the inradius and s is the semi-perimeter of the triangle.
The area of a triangle is equal to the square of its inradius.
The inradius is always half of the area of the triangle.
The area of a triangle can be calculated using the formula: Area = base * height.

How can you find the length of an angle bisector in a triangle?
l = (2ab)/(a+b) * cos(C/2)
l = (a + b) * sin(C/2)
l = (a^2 + b^2) / (2ab) * tan(C/2)
l = (a - b) * cos(C)

What is the semi-perimeter of a triangle?
The semi-perimeter is the sum of the lengths of all three sides.
The semi-perimeter is the average of the lengths of the sides.
The semi-perimeter of a triangle is half the sum of the lengths of its sides, calculated as s = (a + b + c) / 2.
The semi-perimeter is the difference between the longest side and the sum of the other two sides.
