This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The sum of the interior angles in any triangle is always 180 degrees. - The Pythagorean theorem, a² + b² = c², applies exclusively to right triangles to find a missing side length. - Similar triangles have proportional sides and identical angles, often tested with shadow or projection problems. - Memorizing the side ratios for special right triangles (1:1:√2 for 45-45-90 and 1:√3:2 for 30-60-90) is a critical time-saver. - The triangle inequality theorem states any side must be shorter than the sum of the other two, which can help eliminate invalid answer choices.
