Cards Term Rectangle Definition A four-sided plane figure with four right angles. Term Radius Definition The distance from the center point to the outside curved surface. Term Supplemental Angle Definition Two angles added together equaling 180 degrees. Term Acute angle Definition An angle less than 90 degrees. Term Right Triangle Definition A triangle having a 90 degree angle or right angle in it. Term Polygon Definition A closed plane figure with three or more straight sides. Term Point Definition An exact location in space. Term Arc Definition A part of a circle. Term Complementary Angle Definition Two angles added together equaling 90 degrees. Term Center Point Definition The origin of a circle or arc. Term Obtuse Angle Definition An angle greater than 90 degrees. Term Line Definition The path of an infinite series of points. Term Equilateral Triangle Definition A triangle in which all angles are equal and all sides have equal lengths. Term Bisector Definition To divide an angle into two equal parts. Term Diameter Definition The straight distance from one outside curved surface through the center point to the opposite outside curved surface. Term Circle Definition A closed curve with all the points on the circle at the same distance from the center point. Term Isosceles Triangle Definition A triangle which has two sides of equal length and two equal interior angles. Term Circumference Definition The distance around the outside of the circle. Term Ellipse Definition The group or set f all points in the same plane whose sum of distances from two foci is constant. It looks like a squashed circle or a circle viewed at an angle. Term Inscribed Definition A shape drawn inside of a circle. Term Horizontal Definition A line parallel to the horizon. Term Vertical Definition A line perpendicular to the horizon. Term Parallel Definition Two or more coplanar lines having equal distance between them. Term Perpendicular Definition Two lines forming a 90 degree angle. Term Tangent Definition A line touching an arc or circle at only one point. Term Concentric Definition Arcs and circles sharing the same center. Term Collinear Definition Lines or points belonging to the same line, or an extension of a line. Term Coincident Definition Two points fixed together. Term Equal Definition Of the same length. Term Coplanar Definition Belonging to the same plane. Term Chord Definition A straight line with opposite ends that terminate on the circumference of a circle. Term Circumscribed Definition A shape drawn around a circle. Term Hexagon Definition A polygon with six sides. Term Octagon Definition A polygon with eight sides. Term Pentagon Definition A polygon with five sides. Term Quadrilateral Definition A polygon with four sides. Term Rhombus Definition A quadrilateral with four equal sides and opposite angles equal. Term Right Angle Definition An angle measuring 90 degrees. Term Scalene Triangle Definition A triangle with no sides equal and no angles equal. Term Square Definition A polygon with four equal sides and four right angles. Term Trapezoid Definition A quadrilateral with two parallel sides. Term Vertex Definition The point where the two sides of an angle intersect. Term Fixed Point Definition Locking a point to a position relative to the sketch coordinate system. Term Absolute Coordinates Definition A method of plotting points whereby distances are measured from the origin. Term Axis Definition Primary direction in a coordinate system. Term Cartesian Coordinate System Definition A rectangular coordinate system created by three perpendicular axes labeled X, Y, and Z. Term Origin Definition The point at which axes intersect. Term Polar Definition A method of plotting points whereby distances are measured using angles. Term Relative Definition A method of plotting points whereby distances are measured from the previous point. Term The shortest distance between two points. Definition What is a straight line? Term Length Definition Which of the following do lines have: a)length? b)width? c)thickness? Term None of these Definition Which of the following do points have: a)length? b)width? c)thickness? Term Locations in space Definition What are points used to indicate? Term A point can be defined as a set of coordinates (x,y) on the Cartesian plane. Definition How can a point be defined? Term Cartesian Definition The most commonly used coordinate system today for identifying points. Term 180 degrees Definition The sum of the interior angles of a triangle. Term Since there are 360 degrees in a circle, take 360 degrees and divide by the number of sides in the polygon. Definition How do you find the central angle of an inscribed or circumscribed polygon? Term Rhomboid Definition A parallelogram with opposite sides and opposite angles are equal. Term Trapezium Definition A quadrilateral with no sides equal. Term Heptagon Definition A polygon with seven sides. Term Nonagon Definition A polygon with nine sides. Term Decagon Definition A polygon with ten sides. Term (1) Take the given angle. (2) Strike Arc R at any distance. (3) From the two points that Arc R intersect your angle, strike two additional arcs at any given distance (as long as they are equal) (4) Draw a line from the vertex of the angle to where the Definition Tell in list format how to bisect an angle.
