Theorems 1 All right angles are congruent. 2 Perpendicular lines form right angles. 3 If two angles are complements or supplements to the same or congruent angles‚ they are congruent. 4 Two adjacent angles that fall on the same line form a linear pair and are supplementary. 5 Corresponding parts of congruent triangles are congruent. 6 If two sides of a triangle are congruent the angles opposite are congruent. 7 If two angles in a triangle are congruent the sides opposite are congruent. 8 The base

Developed in 1957 with Ronal Nyholm‚ Gillespie has done extensive work on expanding the idea of the VSEPR model of molecular geometry. The theory they created is much more effect to predict‚ explain and describe the 3D molecular shapes (linear‚ pyramidal‚ cubical etc.) based on the number of electron pairs that are found on the outer shell. Their theory is based on electron repulsion

communicate the information necessary to make the idea a reality. In order to generate a 3D model‚ designs must start with sketches that are generated within the CAD program. These computer generated sketches will appear resemble hand drawn sketches in geometry (the combination of points‚ lines‚ and shapes)‚ but have big advantages over hand drawn sketches. One important difference between a freehand sketch and a CAD sketch is accuracy. The lines of a CAD sketch can be drawn perfectly straight‚ with start
