Answer:
Orthocenter of a Triangle
The orthocenter of a triangle is the point where the perpendicular drawn from the vertices to the opposite sides of the triangle intersect each other.
• For an acute angle triangle, the orthocenter lies inside the triangle.
• For the obtuse angle triangle, the orthocenter lies outside the triangle.
• For a right triangle, the orthocenter lies on the vertex of the right angle.
Answer:
The initial step of your eyes detecting the black marks on the page depends on the process of _SENSATION_.
Then the ability to organize the black marks on the paper into meaningful patterns involves the process of PERCEPTION.
Explanation:
Sensation is the detection of external or internal stimulation (e.g, ears detecting sound waves). It is different from perception, which is about making sense of, or describing, the stimulation (e.g.,hearing a guitar).
Sensation involves three steps:
1. Sensory receptors detect stimuli.
2. Sensory stimuli are transduced into electrical impulses (action potentials) to be decoded by the brain.
3. Electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information (perception).
