In math 10, week 3, we went over lots of different things to do with triangles and ratios. Some important details from this are the different types of triangles.
The first one is the Isosceles triangle. This triangle has 2 of the sames sides which only one of the sides different.
The next one is the right triangle, this triangle has one of the inside angles to be 90 degrees. Which is normally on the opposite side of the hypotenuse.
The third triangle is the equilateral triangle, this triangle is a triangle that has all equal side lengths. It is also known as a basic or normal triangle. And each side is at a 60 degree angle.
Finally, the last triangle is the scalene triangle. This triangle has all different sides. Each degree is different and each length is different.
This week we also learned all 3 ratios, them being, Sine ratio, Cosine ration, and the Tangent ratio. The equations for each ratio are…
Sine= opposite/hypotenuse
Cosine= adjacent/hypotenuse
Tangent= opposite/adjacent
