Exploring Diagonals and the Pythagorean Theorem—Corner to Corner
6th - 8th CCSS: Designed
New ReviewPythagoras sure was a smart man. Learners explore diagonals of rectangles by measuring a few of them with a ruler in the second and final installment of a two-part series. Based on the results, they try to come up with a relationship...
Tangent Lines: Lesson
3 mins 8th - 11th CCSS: Adaptable
New ReviewPoint out properties of a line tangent to a circle. The resource provides two theorems dealing with tangent lines to a circle. A section of a geometry playlist uses the relationship between a radius and a tangent line to find missing...
Inverse Trigonometric Ratios: Lesson
5 mins 9th - 11th CCSS: Adaptable
New ReviewFinding the inverse of trigonometric ratios is not the same as finding the reciprocal. The presentation introduces how to find the angle of a right triangle given sides. Part of a larger playlist on geometry, the video uses the inverse...
Special Right Triangle 30-60-90: Lesson
3 mins 8th - 11th
New ReviewIt is special—given one length, you can find the other two. A segment of a basic geometry playlist provides the ratio of the lengths of sides of a 30-60 right triangle. The presentation shows how to use the ratio to find side lengths...
Applications of the Pythagorean Theorem: Lesson
4 mins 8th - 11th CCSS: Adaptable
New ReviewThe Pythagorean Theorem works for something other than right triangles; show your class all it can do. Using information from the Pythagorean Theorem, the video shows how to determine whether a triangle is an acute or obtuse triangle....
Using the Pythagorean Theorem: Lesson
5 mins 8th - 11th CCSS: Adaptable
New ReviewIs it right to use the converse? A segment of a basic geometry playlist introduces the Pythagorean Theorem and its converse. The video uses Pythagorean triples when finding whether a triangle is a right triangle or not.
Build a Cable-Stayed Bridge
3rd - 8th CCSS: Adaptable
New ReviewLarge or small, bridges are architectural wonders! Construct a large-scale cable-stayed bridge during a whole class project. Scholars work in groups to erect the towers, build the roadway, and secure the cables of their very own bridges....
Distance Between Parallel Lines: Lesson
4 mins 9th - 12th CCSS: Adaptable
New ReviewRely on slope when counting won't do. Using horizontal and vertical parallel lines, the presentation shows scholars how to find the distance by counting. The video uses the relationship of the slopes of perpendicular lines to find two...
Finding the Distance Between Two Points: Lesson
4 mins 7th - 10th CCSS: Adaptable
New ReviewPoint out an application of Pythagoras. The segment of an essential playlist on geometry provides a quick review of the Pythagorean Theorem. Using a right triangle to show the positions of two points, the presenter calculates the...
Law of Cosines—Law of Sines and Law of Cosines
9th - 12th CCSS: Adaptable
New ReviewLaws are not always made to be broken! Scholars learn how following the Law of Cosines can help to find unknown measures. They first derive the formula and then apply it to triangles. The activity concludes the two-part series from...
Introduction to the Pythagorean Theorem
4 mins 7th - 10th CCSS: Adaptable
Use a new medium to investigate an old mathematical theorem. Young mathematicians learn about the Pythagorean Theorem from a YouTube video in the Socratica Geometry playlist. They first see if a set of values is a Pythagorean triple and...
