Khan Academy: Similar Triangle Example Problems

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

Although a rather complicated topic, this video clearly explains the concept of solving problems involving similar triangles. It employs problem-solving to determine whether two figures are similar triangles. In addition, it provides...

Building on concepts in the first part of the series on similar triangles, installment number two explores how to find the values for given angles in a triangle. These problems are solved by using algebra and ratios. A step-by-step...

The video from Khan Academy provides practice questions for the SAT. Students will watch Sal work through a right triangle word problem that is more challenging than other examples that are available.

The video from Khan Academy provides practice questions for the SAT. Students will watch Sal work through a basic Right triangle word problem.

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]

Demonstration on how to determine if triangles are similar based on AA, SSS, or SAS similarity postulates.

Solve word problems that involve general triangles using trigonometry. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve word problems by modeling real-world (and not-so-real) situations as right triangles and using trigonometry.
