In lesson 2 of our circles unit, we talk about arcs and their measures, and how they relate to central angles. We add a couple parts to our circle, distinguish between minor and major arcs, and solve problems using arc measures and central angles.
After what seems like years of talking about triangles, we are finally moving into our unit on circles. In this lesson, we learn about the different parts of a circle, compare radius and diameter, and start solving problems with area and circumference. Check out more inside!
A one-stop shop for all things “trig.” In this lesson, we review all of the lessons in our right triangle trigonometry unit and prepare for the Unit 7 Test. Check inside for more details.
We take a more in-depth look at Sin, Cos, and Tan during this lesson, in which we continue our unit on right triangle trig. We learn how we can use these ratios to find the length of missing sides and the measures of missing angles in right triangles.
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.
