hoe can we draw an altitude
no; a triangle must have an obtuse angle if one of its altitudes is outside of the triangle, and in this case 2 of the altitudes are out of the triangle.
3 altitudes.
Yes, except that with a right angled triangle, two of the altitudes will also be the sides of the triangle.
A triangle has three altitudes.
No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.
Draw two altitudes: an altitude is a straight line from a vertex to the opposite side. The three altitudes of a triangle meet at the orthocentre, but two are enough to determine the point.
no; a triangle must have an obtuse angle if one of its altitudes is outside of the triangle, and in this case 2 of the altitudes are out of the triangle.
3 altitudes.
draw a triangle ABC and three altitudes AH BL and CM AH_|_ BC BL _|_AC and CM _|_ AB for right triangle AHB, using Pythagorean AH² = AB² - BH² so AH < AB similarly for other altitudes thus AH+BL+CM is < AB+BC+CA
Yes, except that with a right angled triangle, two of the altitudes will also be the sides of the triangle.
the point of concurrency of the altitudes of a triangle is called the orthocenter.
the point of concurrency of the altitudes of a triangle is called the orthocenter.
A triangle has three altitudes.
Obtuse Triangle
Obtuse Triangle
No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.
The orthocenter of a triangle is found at the intersection of the three altitudes of the triangle. Obtuse triangles contain altitudes which are found outside of the triangle, meaning their orthocenter must be outside of the triangle as well.
