Example Question #3 : Shape Properties

What is the main difference between a right triangle and an isosceles triangle? 

Possible Answers:

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

An isosceles triangle has to have a  angle and a right triangle has to have  equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

Correct answer:

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

Explanation:

By definition, a right triangle has to have one right angle, or a  angle, and an isosceles triangle has  equal base angles and two equal side lengths. 

Example Question #2 : Right Triangles

A right triangle has a hypotenuse of 39 and one leg is 36. What is the length of the other leg?

Possible Answers:

Correct answer:

Explanation:

You may recognize these numbers as multiples of 13 and 12 (each by a factor of 3) and remember that sides of length 5, 12 and 13 make a special right triangle. So the other leg would be 15 .

If you don't remember this, you can use Pythagorean theorem:

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

A right triangle has a hypotenuse of  and one leg has a length of . What is the length of the other leg?

Possible Answers:

Correct answer:

Explanation:

When calculating the lengths of sides of a right triangle, we can use the Pythagorean Theorem as follows:

, where  and  are legs of the triangle and  is the hypotenuse.

Plugging in our given values:

Subtracting  from each side of the equation:

Taking the square root of each side of the equation:

Simplifying the square root:
