Similar Triangles Problem Solving Middle School Essay Examples

Therefore, for identical triangles: $\frac=\frac=\frac=1$ Therefore, all identical triangles are similar. Although the above shows that we need to know the measures of the three angles or the lengths of the three sides of each triangle in order to decide whether the two triangles are similar or not, it would be sufficient, for solving problems involving similar triangles, to know only three of the above measures for each triangle.These measures can be any of the following combinations: 1) the three angles of each triangle (without the need to know the lengths of their sides).She stood in front of the tree and started backing until she could see the top edge of the building from above the tree top.

Scroll down the page for more examples and solutions on how to detect similar triangles and how to use similar triangles to solve problems.

Keep an open mind, and be on the look out for the possibility of several different solution methods.

The triangles seen in this problem are positioned such that their corresponding parts are in the same positions in each triangle.
