Answer 2

The orthocenter of a triangle is the intersection of the three altitudes of the triangle. If the triangle is obtuse, the orthocenter will be outside the triangle.

The altitudes should be drawn as lines, not just line segments. That way you will find the intersection even if it's outside the triangle.

Answer 3

Construct the altitudes for at least two of the sides. The point where they intersect is the orthocenter. It doesn't matter what type of triangle you have. Just remember that for an obtuse triangle that the orthocentre is probably outside of the triangle.

Answer 4

The easiest way to answer this question is with a protractor. First draw a <90 then a 100 To be a right triangle, you need two things: 1. a right angle 2. 3 lines that all connect 3. The sum of the angles (other than the right angle) must equal 90. an obtuse angle is ________ than 90 degrees? (greater or less you fill in the blank!)

Answer 5

Nope
