Example Question #1 : How To Find The Height Of A Right Triangle

If the hypotenuse of a right triangle is 20, and one of the legs is 12, what is the value of the other leg?

Possible Answers:

Correct answer:

Explanation:

The triangle in this problem is a variation of the 3, 4, 5 right triangle. However, it is 4 times bigger. We know this because  (the length of the hypotenuse) and  (the length of one of the legs). 

Therefore, the length of the other leg will be equal to:

Example Question #33 : Properties Of Triangles

A given right triangle has a base of length  and a total area of . What is the height of the right triangle?

Possible Answers:

Not enough information provided

Correct answer:

Explanation:

For a given right triangle with base  and height , the area  can be defined by the formula . If one leg of the right triangle is taken as the base, then the other leg is the height.  

Therefore, to find the height , we restructure the formula for the area  as follows:

Plugging in our values for  and :

Example Question #1 : How To Find The Height Of A Right Triangle

A given right triangle has a hypotenuse of  and a total area of . What is the height of the triangle?

Possible Answers:

Not enough information provided

Correct answer:

Not enough information provided

Explanation:

For a given right triangle with base  and height , the area  can be defined by the formula . If one leg of the right triangle is taken as the base, then the other leg is the height. 

However, we have not been given a base or leg length for the right triangle, only the length of the hypotenuse and the area. We therefore do not have enough information to solve for the height
