## Learn How To Find the Area of a Non-Right Triangle

January 27, 2021 To find the area of a non-right triangle, let’s first review the standard area formula of a right triangle. A right triangle is made up of three sides: the base, the height, and the hypotenuse. To get the area of a triangle you must multiply the two adjacent side lengths of the 90° angle, which are the base and the height of the triangle, and divide this quantity by half. This is the formula for the area of a right triangle: However, this formula doesn't work as effectively for acute and obtuse angles. So here's how to find the area of a non-right triangle.

January 25, 2021 Once you get the hang of rounding numbers, you’ll begin to use it every day, from balancing your checkbook to estimating your grocery bill. In this post, we’ll show you how to round to the nearest tenth (or any decimal place, for that matter).

## How You Use the Triangular Proportionality Theorem Every Day

January 21, 2021 The triangle proportionality theorem is a geometric law stating that when you draw a line parallel to one side of a triangle, it’ll intersect the other two sides of the triangle and divide them proportionally. Regardless of whether they're obtuse, acute, or right triangles, this theorem can be used to determine unknown lengths within similar triangles.

## How To Master Quadratic Regression

January 21, 2021 Similar to functions, quadratic regression is a way to model a relationship between two sets of independent variables. Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax2 + bx + c, where a can never equal zero.

The graphs of quadratic functions have a nonlinear “U”-shape with exponential curves on either side of a single intercepting y-value. We’ll show you how to use this equation.

## Three Types of Geometric Proofs You Need to Know

January 21, 2021 Geometric proofs are given statements that prove a mathematical concept is true. In order for a proof to be proven true, it has to include multiple steps. These steps are made up of reasons and statements.

There are many types of geometric proofs, including two-column proofs, paragraph proofs, and flowchart proofs. We’ll walk you through each type.
