Try geometry before trigonometry. While you can use trig to find every side and angle, geometry is usually quicker and easier. First, remember the sum of the angles of any triangle is always 180 degrees. If you know 2 angles of a triangle, you can always subtract their sum from 180 to ...

Add the values of the three angles in any triangle, and you'll get 180 degrees. If you have a right triangle, one of its angles is 90 degrees by definition. That means the sum of the other two angles has to be 90 degrees, and if you know one of them, you can immediately find t...
A right angled triangle has exactly one of its angle values equal to 90 degrees, which is where the Pythagorean theorem formula can be applied. The side opposite the right angle is known as the hypotenuse and will always be the longest side of the right angled triangle. Triangles without a ...

Learn how to find the missing sides or angles of a right triangle when one length and one angle are provided.
These relationships describe how angles and sides of right triangles relate to one another. Say, for example, we have a right triangle with a 30-degree angle, and whose longest side, or hypotenuse, is a length of 7. We can use our predefined right triangle relationships to figure out the...
They're two-dimensional surfaces that show absolutely precise, three-dimensional images of real objects. You don't even have to wear special glasses or look through a View-Master to see the images in 3-D. If you look at these holograms from different angles, you see objects from different...
We fold a triangle once along a straight line and study how small the area of the folded figure can be. It can always be as small as the fraction 2−2 of the area of the original triangle. This is best possible: For every positive number ε there are triangles that cannot be folded...
