alleryTrigonometric ratios of acute angles were studied as ratios of the sides of a:
ARight angled trisector
BRight angled triangle
CRight angled trapezium
DRight angled tetragon
Answer & Solution
Correct answer: B. Right angled triangle
1. The earlier treatment needed a fixed reference angle.
2. One angle of the figure was a right angle.
3. Trigonometric ratios of acute angles were studied as the ratio of the sides of a right angled triangle.
4. So the answer is a right angled triangle.
