What do you call the longest side of a right triangle?
It's opposite the right angle.
If angle θ = 90° in a right triangle, what are the values of sine, cosine, and tangent?
Consider the definitions of these ratios for a right triangle.
What is the sine ratio of a right triangle?
Remember the acronym SOHCAHTOA.
True or False: The tangent of a 90° angle is defined.
Consider how tangent is formed.
A right triangle has an angle θ = 30° and one adjacent side of 4 cm. Using trigonometric ratios, find the hypotenuse and opposite side.
Use cosine to find hypotenuse first.
A right-angled triangle has a hypotenuse of 13 cm and one side of 5 cm. Find the angle opposite to the side of 5 cm using trigonometric ratios.
Utilize the sine function for finding the angle.
