Hi I'm Charlie Kasov. I'm a math teacher and today we're going to learn about figures that have different kinds of angles. So what are the different kinds of angles? Well, there's acute, which is less than 90 degrees, there's right angle, which is 90 degrees, and then there is obtuse, which is greater than 90 degrees. So a triangle can be can have an acute, like let's say this is 40, and this is 50, and have a right angle. A square has all right angles. A rectangle also has all right angles, but we could have a quadrilateral where it's just four sides and we can have a right angle, a right angle, an obtuse angle, say this is 130, and an acute angle, 50. So these are some basic types of figures that have different types of angles. I'm Charlie Kasov, and you just learned about a few figures with different types of angles.
