SAT : Special triangles Quiz
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 ( a
^{2}
+ b
^{2}
= c
^{2}
, 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.
