Trigonometric Ratios: A Geometer's Perspective
9th - 11th CCSS: Adaptable
New ReviewWhat do all right triangles have in common? Young mathematicians investigate the trigonometric ratios in relation to right triangles. Their investigations lead to a hypothesis they use to determine unknown lengths in different triangles.
Inverse Trigonometric Ratios: Lesson
5 mins 9th - 11th CCSS: Adaptable
Finding 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...
The Trigonometric Ratios: Lesson
6 mins 9th - 12th CCSS: Adaptable
SOH, what is this thing called trigonometric ratios? A section of an extensive playlist on geometry identifies the adjacent and opposite sides in relationship of an angle. Using the identified sides, the video defines the sine, cosine,...
Inscribed Similar Triangles: Lesson
4 mins 6th - 12th CCSS: Adaptable
Create similar triangles with a little altitude. A section of an extensive playlist on basic geometry discusses how an altitude of a right triangle creates similar triangles. Using the theorem, the presentation finds unknown side...
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...
