Questions
What is the formula for the Pythagorean theorem?
a2 + b2 = c2
What is the formula for Sine?
Opposite/Hypotenuse
What is the formula for Cosine?
Adjacent/Hypotenuse
What is the formula for Tangent?
Opposite/Adjacent
a2 is the height of the triangle,
b2 is the base of the triangle
c2 is the slope of the triangle (the diagonal side)
You plus a2 and b2 to get c2, and then square root c2 to get c
What is this formula used for?
To find the opposite side of a right triangle
How can we find the adjacent side of a triangle?
We use an angle of a triangle to see if one side of the triangle is the adjacent or not.
The adjacent side of the triangle is the one that is next to the given angle, and next to the hypotenuse.
How can we find the opposite of a triangle?
We use an angle from a triangle to see if the side of the triangle is the opposite or not.
If the angle is pointing to one side of a triangle, then that's the opposite of the triangle.
How do you find the length of a triangle with the base and height of 8m and 6m?
Square the height and base, plus them together, and square root the answer.
82 + 62 = ?
64 + 36 = 100
square root of 100 = 10
When should we use sin cos tan?
When 2 sides of a triangle is missing or unknown.
