How is the semiperimeter (s) of a triangle calculated?
How is the semiperimeter (s) of a triangle calculated?
- $s = \frac{1}{4}(a + b + c)$
- $s = \frac{1}{3}(a + b + c)$
- $s = \frac{1}{2}(a \times b \times c)$
- $s = \frac{1}{2}(a + b + c)$ (correct)
In the example provided, why is the triangle considered Heronian?
In the example provided, why is the triangle considered Heronian?
- Because it has equal sides
- Because it has a right angle
- Because the side lengths and area are integers (correct)
