Quiz
*Theme/Title: Special triangles
* Description/Instructions

Triangles, especially right triangles, are important to many key concepts that are tested on the SAT. Knowing the Pythagorean Theorem ( a2 + b2 = c2 , where c is the hypotenuse) is crucial, but it's also a good idea to memorize certain right triangles that occur frequently on the exam. In particular, you should be familiar with:

• The right triangle that has sides in the ratio of 3 : 4 : 5

• The isosceles right triangle, which has angles 45, 45, and 90 degrees and whose sides are in the ratio 1 : 1 : $\sqrt{2}$

• The right triangle with angles 30, 60, and 90 degrees, and whose sides are in the ratio 1 : $\sqrt{3}$ : 2 .

In addition, you should look out for any isosceles triangle as well as the equilateral triangle, which has all 60-degree angles.
