Lesson 25 Triangle ratios
Worksheet 3 Sine ratios
Angle | Tangent Opposite/Adjacent | Sine Opposite/Hypotenuse |
10 | ||
20 | ||
30 | ||
40 | ||
50 | ||
60 | ||
70 | ||
80 |
Now try these:
- Can you estimate the sine ratio for 45°? You can check this by drawing and measuring.
- If the hypotenuse in a 45° triangle is 12 cm, what should the opposite side be?
- When you look at the table what do you notice?
- What about angles below 10° and above 80°?
