Answer:
The error Esteban made that the altitude can be lie outside the triangle
Step-by-step explanation:
* Lets explain the position of the altitude in any triangles
- The altitude of a triangle is a line drawn from a vertex to the
opposite side and perpendicular to it
- So altitude is the shortest distance from a vertex to its opposite side
- If the triangle is acute triangle, then its altitudes lie inside it
- If the triangle is obtuse triangle, the the altitudes of the sides of
the obtuse angle lie out side it and the third altitude lies inside it
- If the triangle is right triangle, then the two sides of the right angle
are altitudes of it and the third altitude lies inside it
- Look to the attached figures for more understand
∵ Esteban said the altitude of a triangle always lies inside of or
along the side of the triangle
∴ The error Esteban made that the altitude can be lie outside
the triangle
