If one of the three interior angles is 90 degrees then it is a right triangle.
You find the orthocenter by constructing the altitudes from the vertices in a triangle. If the triangle is obtuse, the orthocenter will fall outside the triangle. If the triangle is acute, the orthocenter will fall on the inside of the triangle. If the triangle is a right triangle, the orthocenter will lie on a vertix.
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
No way! An easy example is the centroid and circumcenter of a right-angle triangle. Circumcenter will be exactly on the middle of the hypotenuse which obviously cannot be the centroid. Centroid is the point where all three lines are connecting all the three vertices and the middle of the line opposite the respective vertex. Circumcenter is the center of the circle passing through all the vertices. As it is known, a right-angle triangle will always fall within a semicircle, meaning the circle center will always be on the middle of the hypotenuse.
One of its interior will be 90 degrees. also there will be a little box in the corner to show that it is a right angle.
Your question doesn't seem to make any sense but if the sides of the triangle are 3, 4 and 5 then it is a right angle triangle because it complies with Pythagoras' theorem.
Vertices are the main property of triangles. No vertices, no triangle.
A right triangle has 3 corners, or vertices.
a right triangle
All triangles have exactly three vertices.
If a triangle has a right angle, it is a right triangle.
3 vertices in a triangle, whether it is equilateral, isosceles or scalene; acute angled, right or obtuse.
Like all triangles it has 3 vertices.

A right angle triangle contains a 90 degree angle and 2 acute angles.
3. Vertex (singular of Vertices) is the POINT of the sides (ray, segment, line) come together. For any triangle it always has 3 angles, and thus 3 points, which means 3 vertices. A right triangle is still an triangle, only that one of the 3 angles being 90 degree.
A right angled triangle.
A triangle has 3 edges and 3 vertices. A triangular prism has 9 edges and 6 vertices.
