In this lesson, we review all of the major concepts of similar triangles that we have covered thus far: solving proportions, finding scale factor, and solving for missing sides.
We also introduce the three ways that can prove two triangles are similar:
- Side-Side-Side Similarity (SSS~)
- Angle-Angle Similarity (AA~)
- Side-Angle-Side Similarity (SAS~)
Dec. 11 Proving Triangles Similar
We continue our unit on similar triangles with this lesson, which focuses on finding scale factor and using it to find the missing sides of similar triangles. Check out more inside!
Dec. 7 Similar Triangles
Now that we’ve conquered congruent triangles, it’s time to switch things up a bit. Check out this lesson for an introduction to similar figures, with some review of setting up ratios and solving proportions.
