In this lesson, we get an introduction to the three basic trigonometric functions: Sine, Cosine, and Tangent. We can use SOH-CAH-TOA to help us remember the relationships between the opposite, adjacent, and hypotenuse sides of a right triangle.
If two is good, then three is even better!
In the third and final part of Semester Exam Boot Camp series, we review our three main formulas (distance, midpoint and slope) and our rules for inequalities in triangles: ordering by sides and angles, finding the range for the third side, and determining if three side lengths can form a triangle. Check out the series finale inside!
Review parallel lines with a transversal in Part 2 of the Semester Exam Boot Camp. We take a look at angle relationships and how they can help you solve problems involving parallel lines. Includes a link to great Kahoot to practice too!
Make sure that you stay on your p’s and q’s with this review of conditional statements. Get some extra practice with symbolic form, Venn diagrams, and drawing conclusions, in preparation for the semester exam.
Let’s kick off the new year with some new shapes! Here we learn about different types of polygons and their angles–both inside and outside.
Enjoy your winter break, and see you in 2018!!
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~)
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!
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.
