The process of drawing the altitude from a vertex to the foot is known as dropping the altitude at that vertex. It is a special case of orthogonal projection. Altitudes can be used in the computation of the area of a triangle: one-half of the product of an altitude's length and its base's length (symbol b) equals the triangle's area: A = h b /2 ...
This implies that the longest side in an obtuse triangle is the one opposite the obtuse-angled vertex. An acute triangle has three inscribed squares, each with one side coinciding with part of a side of the triangle and with the square's other two vertices on the remaining two sides of the triangle. (In a right triangle two of these are merged ...
In an isosceles triangle with exactly two equal sides, these three points are distinct, and (by symmetry) all lie on the symmetry axis of the triangle, from which it follows that the Euler line coincides with the axis of symmetry. The incenter of the triangle also lies on the Euler line, something that is not true for other triangles. [15] If ...
The distance to a star with a parallax angle of only one arcsecond measured on a baseline of one AU is a unit known as the parsec (pc) in astronomy and is equal to about 3.26 light years. [5] There is an inverse relationship between the distance in parsecs and the angle in arcseconds.
The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith.
VILNIUS (Reuters) -Lithuania has found no sign that the crash on Monday of a DHL cargo plane was caused by sabotage, and believes technical issues were a more likely explanation, officials said on ...
A woman in the Sunshine State says she was let go from her job over an act of kindness. On Nov. 27, Florida resident Victoria Hughes appeared on NBC affiliate WFLA to discuss being fired from an ...
Jones dropped a game-high 23 points off the bench for Iowa State while shooting 5-of-8 from behind the arc. Joshua Jefferson added 19 points and 10 rebounds, and Dishon Jackson added 12 points inside.
