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.
In an equiangular triangle, all the angles are equalâeach one measures 60 degrees. An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angleâan angle of 90 degrees. A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angleâit is more than 90 degrees. An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right anglesâeach one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.
