What is the Vertical Angles Theorem?
The Vertical Angles Theorem is a fundamental concept in geometry that states: When two lines intersect, the opposite (or vertical) angles are congruent. This means that the angles that are across from each other at the point where the lines intersect have the same measure. Understanding Vertical Angles Definition and Identification Vertical angles are formed […]
How to Find the Imaginary Part of a Product?
When dealing with complex numbers, finding the imaginary part of their product can seem daunting at first. However, with a bit of practice and understanding of the process, it becomes quite straightforward. What Are Complex Numbers? Complex numbers are numbers that have both a real part and an imaginary part. They are usually written in […]

Theorems Proven with Congruent Triangles
Congruent triangles are triangles that are identical in shape and size. This means their corresponding sides and angles are equal. Using congruent triangles, several important theorems in geometry can be proven. Let’s explore some of these theorems. 1. The Isosceles Triangle Theorem Statement In an isosceles triangle, the angles opposite the equal sides are equal. […]
