How to Prove Triangles are Similar
Students learn the following theorems related to similar
triangles. If an angle of one triangle is congruent to an angle of
another triangle, and the lengths of the sides that include each angle
are in proportion, then the triangles are similar (Side-Angle-Side
Similarity Theorem, or SAS Similarity Theorem). If the lengths of the
sides of two triangles are in proportion, then the triangles are
similar (Side-Side-Side Similarity Theorem, or SSS Similarity Theor

Triangle Angle Sum
This video explains that the sum of the three angles in any triangle adds up to 180 degrees. The importance of this fact in Geometry cannot be emphasized enough. The triangle angle sum theorem is used in almost every missing angle problem, in the exterior angle theorem, and in the polygon angle sum formula. (4:06)

Triangle Side and Angle Inequalities
This video explains why triangle side and angle inequalities are important when solving proofs. In any triangle, the largest angle is opposite the largest side (the opposite side of an angle is the side that does not form the angle). The shortest angle is opposite the shortest side. Therefore, the angle measures can be used to list the size order of the sides. The converse is also true: the lengths of the sides can be used to order the relative size of the angles. (1:54)

Graphing Linear Inequalities from Standard Form
Instructor uses power point to demonstrate how to graph linear inequalities in standard form. Â Examples model finding the x- and y-intercepts, drawing a line through the two intercepts and forming a boundary line. The instructor then discusses whether the boundary line is dashed or solid and which way to shade the inequality, above or below the boundary line.
