Generally, tremor is caused by a problem in the deep parts of the brain that control movements. Most types of tremor have no known cause, although there are some forms that appear to be inherited and run in families.
PROPERTIES OF EQUILATERAL TRIANGLE. 1. All three sides and three angles are equal. 2. The three angles are 60 degrees each. 3. The angle bisectors, the medians and the perpendicular bisectors of the three sides coincide. It is also the centroid. 4. The incenter and the circumcenter coincide and are within the triangle. 5.
Short Answer: no <br /><br /> Long Answer: <br /> Most people consider Euclidean Geometry when taking about standard shapes such as triangles and squares. <br /><br /> In Euclidean Geometry: all equilateral triangles have angles of 60Â°. Therefore an equilateral triangle doesn't have a right angle. <br /><br /> However, in Non-Euclidean Geometry (Elliptic Geometry) a triangle can have all angles at 90Â°. Consider going for a walk at the North Pole.
