1. COORDINATE GEOMETRY Classify with vertices
... Test choice F. None of the vertices are labeled O. This is incorrect Test choice G: Segment XC connects the third vertex of the triangle to the first vertex. However; segment ML connects the second vertex of the triangle to the third vertex. This is incorrect. Test choice H: Angle X is the third ver ...

Lecture 1: Trigonometric Functions: Definitions
... cos(90◦ ) = 0. Note that tangent is not defined for 90◦ . 1.2 Extending the definitions We now extend the definitions of sine, cosine, and tangent to functions on all of (−∞, ∞). To do so, we first note that we may restrict our discussion to right triangles with hypotenuses of length 1. In that case ...

nSpire activity
... Open the TI-Nspire document Interior_Angles_of_Regular_Polygons.tns. A regular polygon is a closed figure in a plane that is equilateral and equiangular. Therefore, the sides of a regular polygon are congruent, and the angles are also congruent. In this activity, you will explore the interior angles ...

Investigation 1 • Which Angles Are Congruent?
... Repeat Step 1, using the intersecting lines you drew on this worksheet, but this time rotate your patty paper 180° so that the transversal lines up again. What kinds of congruent angles have you created? Trace the lines and angles and mark the congruent angles. Are the lines parallel? Check them. ...
