## Classification of Triangles

Triangles are classified based on two different characteristics: Whether or not the triangle has equal sides and; The size of the angle. Classification Based on Side Length  Scalene This type of triangle has no equal sides.   Isosceles This type of triangle has 2 equal sides. Equilateral All sides of the triangle are equal. Note:…...

As we reviewed in a previous post, there are many different types of quadrilaterals. In this post we will be looking at the individual properties of each. Square   All angles are equal at 90 degrees All sides are of equal length Opposites sides are parallel The diagonals bisect each other at 90 degrees (you…...

Note the beginning of the word quadrilateral is quad  and means 4. In this post we will look at shapes that have 4 sides, 4 vertices and four angles. The image above contains quadrilaterals only. All have the shapes have 4 sides, vertices and angles. Quadrilaterals can be divided into groups based in properties of quadrilaterals.…...

## Acute, Right and obtuse Angles

Acute Angle These angles are smaller than 90 degrees. Right Angle Right angles are equal to 90 degrees. Obtuse Angle An obtuse angle is greater than 90 degrees. Read more →...

## Introduction to Geomerty

Just for a bit of history, Euclid of Alexandria, was a Greek Mathematician and is known as the Father of Geometry. The basics of all geometry taught today can be traced back to him. Discussed in this post are explanations of essential principles for further education in geometry. As we move on, remember that you…...
