I'm a picture learning type of person). please help i do not know it, ~Please ~ help ~ me ~ with ~ these ~ questions.....~ No, obtuse triangles do not have their orthocenter No, right triangles do not have their orthocenter Yes, every triangle has its orthocenter No, some scalene triangles do not have their orthocenter The orthocenter is located inside an acute triangle, on a right triangle, and outside an obtuse triangle. Are her values correct? (Where inside the triangle depends on what type of triangle it is – for example, in an equilateral triangle, the orthocenter is in the center of the triangle.) It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. Please please help please and show work I have 20 questions like this please, 57 - ( - 13 ) = Hence, in a right triangle, the vertex of the right angle is where you would expect the altitudes to meet, at 90 degrees, where the legs of the right triangle are perpendicular. In right angle triangle the orthocenter is on the perimeter of You find a triangle’s incenter at the intersection of the triangle’s three angle bisectors. Kelly is trying to work out the two values of w for which 3w - W3 = 2 This is identical to the constructionA perpendicular to a line through an external point. You can find where two altitudes of a triangle intersect using these four steps: Find the equations of … For an acute triangle, it lies inside the triangle. I have collected several proofs of the concurrency of the altitudes, but of course the altitudes have plenty of other properties not mentioned below. In an isosceles triangle (a triangle with two congruent sides), the altitude having the incongruent side as its base will have the midpoint of that side as its foot. Write an exponential function to describe the given sequence of numbers. If the triangle is an obtuse triangle, the orthocenter lies outside the triangle. …. In acute and right triangles, the Orthocenter does not fall outside of the triangle. However,  when the triangle in question is obtuse, that is, when one of its interior angles measures more than 90 degrees – the Orthocenter will be located outside the triangle. Incenters, like centroids, are always inside their triangles.The above figure shows two triangles with their incenters and inscribed circles, or incircles (circles drawn i… An orthocenter is the point at which all the three altitudes of the triangle intersect each other. In obtuse triangle , the orthocenter lies outside the triangle because all the three altitudes meet outside . This is done because, this being an obtuse triangle, the altitude will be outside the triangle, where it intersects the extended side PQ.After that, we draw the perpendicular from the opposite vertex to the line. Hence, they are called obtuse-angled triangle or simply obtuse triangle.
