Simulators are a great way to model an experiment without actually performing the experiment in real life. This tutorial looks at using a simulator to figure out what might happen if you randomly guessed on a true/false quiz.
You can use sine to help you find the area of a triangle! All you need is two sides and an angle measurement! This tutorial helps you find this formula.
If you need to find the area of a regular polygon all you need is the apothem! This tutorial shows you how to find the area of a regular pentagon when you only know the apothem.
When you're working with similar figures, knowing the scale factor can help you find all sorts of pieces including side measurements and area. This tutorial shows you how to use the scale factor to help find the area of one of the figures.
This tutorial gives you practice finding geometric probability. Given a circle inscribed in a square, you'll see how to find the probability that a point chosen at random will land in the circle!
