2D Geometry Points, Distances, and Directions
... Rotations are another fundamental concept of 2D computational geometry. The good news is that only one rotation, the left rotation by 90 degrees, needs to be used very often. Nevertheless, understanding rotations is the easy way to understand other concepts such as the scalar product of vectors defin ...

2.2 Analyze Conditional Statements
... When pairs of statements are both true or both false, they are called equivalent statements. • A conditional and its contrapositive are equivalent. • An inverse and the converse are equivalent. – So if a conditional is true, so its contrapositive. ...

Properties of Triangles
... Draw the interior of a triangle: Click on the arrow tool. Then click on all three vertices of the triangle. You should see large dots over each of them. Click the mouse on the menu item construct, then on polygon interior. Draw a four-sided figure: Once you have drawn it, resize it by moving one of ...
