6 If the altitudes of a triangle meet at one of the triangle’s vertices, then the triangle is 1) a right triangle

2) an acute triangle

3) an obtuse triangle

4) an equilateral triangle

1) a right triangle

Step-by-step explanation:

One of the caractheristics of a right triangle, the one in which the sum of the two sides squared is the hypotenuse squared(Pytagorean Theorem), is also the the altitudes of a triangle meet at one of the triangle’s vertices. So 1) is the answer to this question.
