INDIVIDUALIZED DRAFTING PROGRAM

Geometric Construction 1. A ________________ represents a location in space or on a drawing, and has no width,

height, or depth. 2. A point is represented by the intersection of two lines (a). (b). 3. Never represent a point by a simple _____________ on the paper. 4. A ________________ _______________is the shortest distance between two points. 5. Either straight lines or curved lines are __________________if the shortest distance between them remains constant. 6. A common symbol for parallel lines is ________ and for perpendicular lines is _____ . 7. An angle is formed by two intersecting lines. A common symbol for an angle is _____. 8. There are 360 degrees in a full circle. A degree is divided in to 60 __________ and a minute is divided into 60 ___________________ . 9. Two angles are _________________________ if they total 90 degrees. 10. Two angles are ___________________________ if they total 180 degrees. 11. A _______________________ is a plane figure bounded by three straight sides, and the sum of the interior angles is always 180 degrees. 12. A ____________________ triangle has one 90 degree angle. 13. A _______________________ is a plane figure bounded by four straight sides. 14. If the opposite sides are parallel, the quadrilateral is also a ____________________. 15. A ______________________ is any plane figure bounded by straight lines. 16. A ____________________is a closed curve all points of which are the same distance from a point called the center. 17. ________________________ refers to the circle or to the distance around the circle.

18. Solids bounded by plane surfaces are ________________________ . 19. A ____________________ has a polygon for a base and triangular lateral faces intersecting at a common point called the vertex. 20. A __________________ is generated by a straight line, called the generatrix, moving in contact with a curved line and always remaining parallel to its previous position or to the axis.
