1. Right Triangle
Trigonometry
By: Molly Mahoney

2. Technology Integration
• Often times when thinking about
technology integration within a classroom
one does not think about the benefits it
may hold for right triangle trigonometry.
• However, instead of having students draw
many different triangles to practice the
Pythagorean theorem it is much more
beneficial to use a program such as Cabri
Geometry where student’s can
manipulate the triangle using different
angles and measurement.
• Not only that, but with technology
graphing common trigonometric
equations can become much easier.

3. Internet Content
• The internet offers a wide array of programs and
resources that can help students gain hands on
experience with the real world uses of right triangle
trigonometry. In addition to using education
programs there are countless numbers of blogs,
podcasts, and videos dedicated to this subject
• The next three slides are an examples of some of
these resources.

7. Internet Resources
• The internet provide a wide array of reliable
resources from government and private
organizations that show the relationship of right
triangle trigonometry and the real world.
• The next two slides are examples of a few reliable
organizations that present this right angle
trigonometry as it relates to their organization.

8. Some examples
• NASA
• This link provides an introduction on right triangle
trigonometry as well as the ways in which it relates
to air crafts and propulsion.
• Khan Academy
• The Khan Academy is a non profit organization that
offers information and tutorials on a variety of
subjects including trigonometry and geometry.
