In a triangle , if then is
Determine the ratio of .
Step 1: Determine the angles of the triangle.
Given,
Assume , then
Thus,
Step 2: Determine the ratio
Since two angles are equal, the triangle is an isosceles right angle triangle and hence two sides will be equal.
Therefore let sides
Thus we have, by the converse of Pythagoras theorem
The ratio of is .
Hence, option (C).is correct .
