Q
What is the longest side on a right-angled triangle called?
A
Hypotenuse (h)
2
Q
What symbol is given to the angle in a right angled triangle?
A
Theta θ
3
Q
Where is the adjacent side in a right angled triangle?
A
Next to the angle.
4
Q
Where is the opposite side in a right angled triangle?
A
Opposite the angle.
5
Q
What are the three equations for right angle triangles?
A
sin(θ) = o/h
cos(θ) = a/h
tan(θ) = o/a
6
Q
How do you find opposite side length in right angled triangles?
A
h x sin(θ) = o
7
Q
How do find the length if the adjacent side in right angled triangles?
A
h x cos(θ) = a
8
Q
How can you find the hypotenuse using sun or cos?
A
h = o/sin(θ)
h = a/cos(θ)
