When you think of Geometry, it’s quite possible you first think of triangles, circles, and squares, maybe even parallelograms. But, how often have you thought about hexagons? Perhaps not as...

Finding the perimeter of a triangle can help you to figure out how much material you need to build a structure. You can also compare the distance you would need to walk around two different triangles...

You might already be familiar with finding the area of a circle.  However, finding the area of a sector takes an extra step, since we are finding just a part of the area. So, what do you need...

You might be familiar with finding the circumference (perimeter) of a circle.  However, finding the arc length takes an extra step, since we are finding just a part of the circumference. So,...

In trigonometry, you will sometimes see common input angles (such as 45 or 90 degrees) for the tangent function.  It is helpful to become familiar with the corresponding outputs for these angles...
