Special Relationships Within Right Triangles - Dividing into Two Similar Sub-Triangles
Read the Fine Print
Rating
0.0 stars

Students understand that the altitude of a right triangle from the vertex of the right angle to the hypotenuse divides the triangle into two similar right triangles that are also similar to the original right triangle. Students complete a table of ratios for the corresponding sides of the similar triangles that are the result of dividing a right triangle into two similar sub-triangles.

Rating
0.0 stars

Students extend what they learned in Module 3 about how multiplying the parent function by a constant or multiplying the x-values of the parent function results in the shrinking or stretching (scaling) of the graph of the parent function and, in some cases, results in the reflection of the function about the x- or y-axis.
