Question

1. What are the three sides of a right angled triangle known as with respect to an angle?

2. Define Sine, Cosine and Tangent of an angle.

3. If the two sides of a right angled triangle are 6 cm and 8 cm, what is the length of the hypotenuse?

4. What are the maximum possible values for sine, cosine and Tangent?

5. In the example beginning at 3:51, Find AB& BC if the angle theta = 30 degrees and AC = 10 cm.

6. In the example beginning at 6:15, If the velocity is 5 m/s and the angle is 45 degrees, Find AC and BC.

7. Use your calculator to find the values of SIne, Cosine and Tangent for the following angles:

a) 0, 30,45,60,90 (all in degrees)

b) Do you notice any pattern? If so describe the pattern in your own words.

1) side opposite to the right angle is called hypotenuse

side adjacent to right angle triangle are called legs

2) sine = height / hypotenuse

cosine = base / hypotenuse

tangent = height / base

3) length of hypotenuse = sqrt(6^2 + 8^2) = 10 cm

4) maximum value of sine and cosine is 1

maximum value of tan is infiite
