New ReviewExplore some right triangle trigonometry with a straightforward video lesson. The instructor presents problems requiring scholars to use trig ratios to find unknown side measures. She provides worked-out solutions for those needing...
The Pythagorean Theorem
13 mins 4th - 8th CCSS: Adaptable
New ReviewBe sure the class gets this one right. Using a right triangle, the video introduces the Pythagorean Theorem. The presentation breaks down the theorem into its components while providing uses of the Pythagorean Theorem and its converse.
Justifying SSS Congruence
9th - 12th CCSS: Designed
New ReviewAre congruent corresponding sides of two triangles enough to show congruence? The short assessment provides two triangles with the information that the three sets of corresponding sides are congruent. Pupils develop a proof showing that...
Special Triangle Ratios: Special Right Triangle Ratios
9th - 12th CCSS: Designed
Go from one side length to any other side length with special right triangles. Individuals use the interactive to investigate the ratio of sides in 45-45 and 30-60 right triangles. Scholars make generalizations about the types of special...
What are Equilateral, Isosceles, and Scalene Triangles?
6 mins 5th - 8th
Triangles are classified by their angle measurement as well as by the length of their sides. Here are some names that identify the types of triangles: right, isosceles, equilateral, scalene, obtuse, and acute. Watch this video to learn...
How Do You Find a Missing Side of a Right Triangle Using Cosine?
5 mins 6th - 11th
Trigonometry? What's trigonometry. Well, something to do with triangles, right? Right! Right triangles! In this problem, find the missing length of one of the sides. So set this up as a ratio: cosine(A) = adjacent side length divided by...
How Do You Determine if a Triangle Is a Right Triangle if You Know its Sides?
3 mins 6th - 10th
Use the Pythagorean Theorem formula to check if this given triangle, with the given lengths of each side, is a right triangle. It's as simple as plugging the given values into the formula and doing the math to see if the solution checks...
How Do You Find the Length of a Leg of a Right Triangle?
4 mins 6th - 9th
A right triangle. Two given measurements for two side lengths and one unknown length. Use the Pythagorean theorem to solve this problem and find the missing value. Squares and square roots are used in this problem and don't worry when...
How Do You Find Missing Measurements of Similar Figures Using a Proportion?
6 mins 6th - 8th
Two similar triangles have the same angles, but their legs have different lengths. This means their angles are congruent, and thusly, their corresponding sides are congruent. So there is a missing measurement that needs to be found. Set...
