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.
Special Right Triangles. 30-60-90 Triangles. An equilateral triangle is a triangle with all sides congruent. From the Isosceles Triangle Theorem if follows that the angles of an equilateral triangle are all the same. Since the angles of any triangle add to 180 o, each angle of an equilateral triangle must be 60 o.n equilateral triangle is a triangle with all sides congruent.
