In the usual sense of things (Euclidean Geometry), no. You could have a 'degenerate triangle', but that's not exactly a triangle in the way we usually think about a triangle. 8 + 7 = 15. So …

## Fractional Exponents, Logarithms, Quartic and Cubic Equations

We started by looking at some current homework which involved factoring. For most of the problems they started with a quartic or cubic equation and then factored into a quadratic and one or two other …

## “How many radians are in 180 degrees?”

180 degrees is the angle of half a circle. 360 degrees is the angle of a full circle. In radians, a full circle is 2π. So half of that is a half circle and half of 2π is π. If 180 degrees …

## How to find the length of a square given the perimeter?

If you have the perimeter of a square, the outside is made of four equal sides. After that I would draw in the diagonal and see that it forms a right triangle, you can also notice that it forms a …

## Geometry Problem with Regular Hexagon

Since the side lengths of the hexagon are all equal, it is a 'regular' hexagon. Therefore all the interior angles of the hexagon are equal. To find the sum of the interior angles of the regular …

## “How can I find the height of a cone by only knowing the radius and length of the side?”

The cross section of a cone is a right triangle, if you know that you can use the Pythagorean theorem. …
