Topic Trigonometry Background
1. GOT IT! [15 MIN]
Basic background that is needed for Grade 10 Trigonometry:
The inside of a triangle is equal to 180°. We will only be looking at the right-angle triangle
90° − ∅ ∴
∅
To calculate the sides of a right-angle triangle, we will make use of the Pythagoras rule
𝑟𝑟 2 = 𝑥𝑥 2 + 𝑦𝑦 2
𝑦𝑦 𝑟𝑟
𝑥𝑥 ∅
The base of the triangle is
dependent on the given angle
We can make use of 𝑠𝑠𝑠𝑠𝑠𝑠 ∅; 𝑐𝑐𝑐𝑐𝑐𝑐 ∅; 𝑡𝑡𝑡𝑡𝑡𝑡 ∅ to determine the angle or side of the triangle, by making use of
trigonometry ratios.
