SAT Math Question (14) - Basic Trigonometry

in #mathematics7 years ago (edited)

I love basic trigonometry! It is so easy once you get the concept, so teaching it is no problem! Here is a guide to what you may see on the SATs. Enjoy my friends!

Right Triangles with Labeled Sides

There are only so many they can give you... H - Hypotenuse (opposite the right angle), O - Opposite (opposite the given angle, theta), A - Adjacent (touching the given angle, theta).

Nice post! But I guess you sould have identified the perpendicular, base and hypotenuse as 'p', 'b' and 'h' respectively. I mean it will help readers to not get puzzled. Thank you :)

Thank you for the advice splash! I will try to clarify it.

Your always welcome :)
