• Today, we will be discussing the last few of our vocabulary words.
• Most of these are words you have heard before, but today, we’ll be talking about them in a bit of a different way.

POLYGONS BY NUMBERS
• There are three names for triangles based on their angles.
• They are obtuse, acute and right.• There are three names for triangles based on
their sides.• They are equilateral, isosceles, and scalene.

POLYGONS BY NUMBERS
• Obtuse triangles have one angle that is larger than 90⁰.
• Acute triangles have only angles that are smaller than 90⁰.
• Right triangles have one angle which is exactly 90⁰.

POLYGONS BY NUMBERS
• Equilateral triangles have all sides of the same length.
• Isosceles triangles have two sides of the same length.
• Scalene triangles have no sides of the same length.

POLYGONS BY NUMBERS
• The perimeter of a triangle is calculated by adding all the side lengths together.
• The area is found by ½ base x height. • Most often, for now, we’ll be working with
right triangles.

• Next up is a square.• A square is a polygon with four congruent
sides and four right angles.

POLYGONS BY NUMBERS
• A polygon is a two-dimensional, closed figure formed by three or more lines.
• All of the figures we have discussed thus far are polygons.

POLYGONS BY NUMBERS
• The perimeter is the distance around the outside of a polygon.
• We can find this on polygons that are on the coordinate plane.
• To do so, we use the distance formula.

• Lastly, a theorem is a math statement proven to be true.
• We will be using theorems in our study of proofs.
• A proof is a stepwise series of reasoning leading us from a given statement to desired conclusion

POLYGONS BY NUMBERS
• For instance, a type of proof you may be asked to do is to prove that a certain figure, is indeed that figure.
• You can do so by proving their properties.
