(2) In any isosceles triangle, the angles opposite the isometric sides are isometric. (3) In any right triangle, the acute angles are complementary. (4) In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. (5) The segment joining the midpoints of the non-parallel sides of a trapezoid is parallel to the bases and its length is one-half the sum of the lengths of the bases. (6) Three non-collinear points determine one and only one circle. (7) In a circle, the measure of the central angle is equal to the degree measure of its intercepted arc. (8) The diagonals of a parallelogram bisect each other. (9) If two sides and the contained angle of one triangle and the two corresponding sides and contained angle of another triangle are isometric, then the triangles are isometric. (10) If the lengths of two sides of one triangle are proportional to the lengths of two sides of another triangle and the contained angles are isometric, then the triangles are similar. 2.Multiple choice ()(1) In Rectangular Plane Coordinate System and , ，determine the coordinate of the point C.（ ）（A） （B） （C） （D） (2) what is the condition between “” and “” （ ）（A）Unnecessary and sufficient condition（B）Need not sufficient condition（C）Sufficient and Necessary Condition （D）Neither fully nor necessary condition(3) The “” is the sum of the n terms of a sequence, if “”, determine “”（ ）（A） （B） （C） （D）(4) If the asymptote of a hyperbola equal to another asymptote of a hyperbola “”, and they through the point , determine the hyperbolic equation.（ ）（A） （B） （C） （D） or (5) The directrix of papabola is the tangent of the circle .
