Question

Which statement about an altitude of a triangle is always true?

An altitude intersects another altitude at the centroid.

An altitude intersects another altitude at its midpoint.

An altitude is present inside a triangle.

An altitude makes a right angle with a side of the triangle.

Answer 1

I think it is the one with the right angle with the side of the triangle.

Answer 2

thank you! can you help me with another one?

Answer 3

How can you check if a segment is an angle bisector of a triangle?

Check if measures of the two angles the segment divides the vertex angle into are the same.

Check if the areas of the two triangles the segment forms are equal.

Check if the segment meets a side of the triangle at a right angle and divides the vertex angle into two congruent angles.

Check if the segment meets a side of the triangle at a right angle and divides the side into two congruent parts.

Answer 4

By definition, an altitude of a triangle is the segment perpendicular to the segment opposite the vertex it intersects.

Answer 5

So it would make a right angle with another side? Correct?

Answer 6

Yes, correct

Answer 7

So my first answer was right?
