Question

Please write your answer clearly on this paper in the spaces provided; identify each statement as true( T) or false( F): Making a conjecture from your observations is called inductive reasoning. The 25th term in the -2, 4, -6, 8, -10,...) sequence is-42 1.( 2.) 3.() A polygon with 7 sides is called a septagon 4.( Ifa polygon is equiangular, then it is equilateral. 5. The complement of an acute angle is an obtuse angle. 6. An angle bisector in a triangle bisects the side it is drawn to. 7. Any point on the altitude drawn to a side of a triangle is equally distant from the two end points of the side. A classical geometric construction uses only these tools: compass and straightedge. The incenter of a triangle is the point of concurrency of the three angle bisectors of the triangle. Non-vertical, non-horizontal perpendicular lines have slopes that are reciprocals of each 8.( 9.( 10.( other. 11.() If the diagonals of a quadrilateral 12. If the base angles of an isosceles triangle each measure 43°, then the vertex angle has a measure are congruent, then the quadrilateral must be a rectangle. of 94° 13.( The measure of each angle of an isosceles triangle is 60° 14. The smallest angle in a scalene triangle is opposite the largest side. 15.( )If point A has coordinates ( 8,-6) and point B has coordinates (-4, 12) , then themidpoint M of AB is (2,3). 16.() If point A has coordinates ( 4,-6) and point B has coordinates (-11,4), then the slope of AB is -2/3 17.The slope of a straight line on the coordinate plane is given by the formula m- Run /Rise. 18.( SAS and AAA are two shortcuts for showing that two triangles are congruent. 19.( The sum of the measures of any two angles of a triangle is greater than the supplement of the third angle The sum of the measures of the vertex angles of a pentagon is 540 °. 20.(
