Why sin30=1/2 |
|
Answer» It\'s reason is given in the text book please read it carefully. Construct right angle triangle ABC1. Draw an arbitrarily long 2. Mark any point namely A on it and use protractor to mark 30° from A and draw another long line 3. Mark point C on the initial line that you drew and again, use the protractor to mark 90° to AC. 4. Extend the 30° from line A and the 90° from line C until they meet 5. Let the point of intersection B and measure the ratio of BC/AB and will be 0.5 or 1/2 |
