  • Special Right Triangles - 30 60 90 and 45 45 90 Triangles

    For a complete lesson on special right triangles, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that in a 45-45 Access full lesson containing this video at: http://www.yourteacher.com/geometry/3... Students learn that in a 45-45-90 triangle, the legs are congruent, and the length of the hypotenuse is equal to root 2 times the length of a leg. Students also learn that in a 30-60-90 triangle, the length of the long leg is equal to root 3 times the length of the short leg, and the length of the hypotenuse is equal to 2 times the length of the short leg. Students are then asked to find the lengths of missing sides of 45-45-90 and 30-60-90 triangles using these formulas. (more) (less)

  • How to Graph a Piecewise Function

    Learn how to graph piecewise functions. A piecewise function is a function which have more than one sub-functions for different sub-intervals(sub-domains) of the function's domain. To graph a piecewice function, we graph the different sub-functions for the different sub-intervals of the function's domain.

  • Thinking about shapes of distributions | Data and statistics

    Some distributions are symmetrical, with data evenly distributed about the mean. Other distributions are "skewed," with data tending to the left or right of the mean. We sometimes say that skewed distributions have "tails."

    Join us as we explore the five triangle congruence theorems (SSS, SAS, ASA, AAS, and HL). By the end of this lesson, you will be able to identify each theorem and understand which scenarios they can be applied in. Oh yeah, and you'll learn to avoid the donkey theorem :)

    This lesson answers the questions: How do I prove that two triangles are congruent? What are the triangle congruence theorems? What is SSS? What is SAS? What is ASA? What is AAS? What is HL? How do I prove triangles using hypotenuse leg?

    Our lessons are perfect for flipped classroom math teachers and students. This lesson is aligned with the common core learning standards for math and the SAT math curriculum as well.
