Learn more about the geometry of straight lines, and we will focus on the relationship between angles formed by perpendicular lines, and intersecting lines. By the end of this lesson, you will be able to describe, and apply these. But before we start our lesson, did you know that astronomers use geometric formulas, to measure the distance from the earth, to other planets and objects in space.

Geometry of Straight Lines Part 2
Did you know that bankers, and financial analysts, use formulas, to calculate interest and loans. To continue from the previous lesson we will learn more about the geometry of straight lines, and the relationship between angles, formed by parallel lines, and cut by a transversal. By the end of th...

Geometry of 2D Part 1
We will focus on the definitions and properties of quadrilaterals. By the end of this lesson, you will be able to find definitions and properties of quadrilaterals.

Geometry of 2D Part 2
We will be focusing on defining properties of triangles, similar and congruent triangles, and solving geometric problems. By the end of this lesson, you will be able to find and describe similar and congruent triangles, you will also be able to use properties, of different shapes, to solve problems.
