How do you find all of the sides for a equilateral triangle

The video tutorial addresses common misconceptions about triangle angles and side lengths. It explains that while angles in a triangle add up to 180 degrees, side lengths do not have a similar rule. The tutorial focuses on solving for X when given equal side lengths and demonstrates how to calculate the values of specific lines. It also discusses verifying equations and handling different numerical scenarios.

Explain the misconception regarding angles and side lengths in triangles.

If X equals 5, what is the value of line QR if QR is expressed as 5X?
