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 equilateral triangle, all sides are the same length. An equilateral triangle is also a regular polygon with all angles 60Â°. In an isosceles triangle, at least two sides are equal in length. An isosceles triangle also has two equal angles: the angles opposite the two equal sides. In a scalene triangle, all sides and internal angles are different from one another. By internal angles. Triangles can also be classified according to their internal angles, measured here in degrees.
