Summary
A tutorial on calculating the area of triangles using Heron's Formula for SSS scenarios and trigonometric formulas for SAS scenarios.
Highlights
Calculating Area with Heron's Formula (SSS)00:00:01
Explanation of how to find the area of a triangle when all three sides are known. It covers calculating the semi-perimeter (s) and applying Heron's formula (sqrt(s(s-a)(s-b)(s-c))) with a practical example.
Calculating Area with Side-Angle-Side (SAS)00:02:42
Instructions for finding the area of an oblique triangle when given two sides and an included angle using the trigonometric formula: Area = 1/2ab*sin(C). The video details how to select the correct formula based on the available variables.
Practical Example of SAS Method00:04:02
A step-by-step walk-through applying the SAS area formula to a specific triangle with sides of 20 and 25 and an included angle of 30 degrees to reach a result of 125 square units.
