Explains how to determine unknown side lengths of similar triangles by identifying corresponding sides and angles ans setting up proportions. The first example is a continuation from the video "Similar Triangles." Practice problems...

Explains how to solve a given word problem that involves similar triangles. The problem requires that two unknown side lengths be determined. [5:34]

Explains how to determine unknown side lengths in a complex diagram that involves similar triangles. [9:53]

Explains how to identify and use similar triangles in order to determine unknown side lengths in two given diagrams. Each diagram also applies knowledge of angles formed when parallel lines are cut by a transversal. [7:37]

Explains how to determine unknown side lengths in a diagram that involves similar triangles where the two triangles share a side and the shared side corresponds to two different sides in each triangle. [6:05]

This video tutorial [8:35] identifies the parts of a right triangle and demonstrates how to use the Pythagorean Theorem to determine an unknown side length of a right triangle.

This video tutorial is n introduction to the Pythagorean theorem. The instructor explains how to use the Pythagorean theorem to find the length of the hypotenuse or the length of one of the legs. At the end of the video, practice...

The video tutorial lesson [9:36] explains how to use the Pythagorean theorem to find the length of the hypotenuse or the length of one of the legs. Introduces the relationship between the length of the legs and the length of the...
