Learn how to determine the surface area of a triangular pyramid

The video tutorial explains how to determine the lateral surface area of a pyramid with a regular polygon base, specifically a triangle. It covers the formula for lateral surface area, visualizes the net of the pyramid, and calculates the perimeter and height. The tutorial also discusses finding the area of the base triangle using trigonometry and combines these calculations to find the total surface area.
