Question
In this 45-45-90 triangle, I have been given a leg, so to find the other leg I...
- Multiply that leg by 2
- Use the same length for the second leg
- Multiply that leg by √2
- Divide that leg by √2
Hint:
We are given a right-angled triangle. One of the angle of triangle is 45°. Length of one side is 5. The length of another leg is given by variable y. The value of hypotenuse is given by a variable x. It is 45°-46°-90° triangle. We are given the value of one leg, so we have to tell how we will find the another leg.
The correct answer is: Use the same length for the second leg
We are given a 45°-45°-90° triangle.
It means two angles of the triangle are same. This happens when the two sides, other than the hypotenuse are equal. So, the given triangle is hypotenuse.
We are given the value of one leg. The other leg will be equal to the first leg.
So, to find the another leg we should use the same length for another leg.
The option which says 'Use the same length for second leg', is the right option.
We should know the properties of different triangles.
