# What is Latus Rectum in Geometry?

For many students, geometry can be a confusing and intimidating subject. There are so many different terms and concepts to learn that it can be difficult to keep track of them all. One term that often comes up in geometry is latus rectum. So what is latus rectum? Let’s take a look at what this concept means in the world of geometry.

## What is Latus Rectum?

In geometry, latus rectum (plural: latera recta) refers to the chord or straight line segment that passes through both foci of an ellipse, or the center of a hyperbola. This line intersects with the major axis at two points and is perpendicular to it. The length of the latus rectum is equal to twice the distance from one focus to any point on the ellipse or hyperbola along its major axis, which makes it easier for mathematicians to calculate distances between points on these curves.

The name "latus rectum" comes from Latin, where “latus” means “wide” and “rectum” means “straight." Thus, when combined, they form a phrase meaning “wide straight," referring to how this line extends directly across the widest part of an ellipse or hyperbola.

## Latus Rectum Impact Geometry?

Latus rectum plays an important role in understanding geometry problems involving ellipses and hyperbolas because it helps mathematicians accurately measure distances between points on these curves. Knowing how long a latus rectum is can also help mathematicians determine other properties about an ellipse or hyperbola such as its eccentricity or area. In addition, understanding how long a latus rectum is can help solve more complex mathematical equations such as those involving conic sections.

## Conclusion:

Latus rectum plays an essential role in understanding many common geometric problems involving ellipses and hyperbolas. It is essentially a chord or straight line segment that passes through both foci of an ellipse or hyperbola and helps mathematicians accurately measure distances between points on these curves. Knowing how long a latus rectum is can also help solve more complex mathematical equations such as those involving conic sections, making it an invaluable tool for students studying math!
