In this animated lesson, we explore a cleverly constructed diagram involving two right triangles and just one shared angle, x. You’ll learn how to use basic trigonometric identities like sine, cosine, tangent, and cotangent to calculate and compare triangle areas — without any given lengths!
We walk through:
How to label and name key angles
How to assign convenient values to simplify the math
How to express side lengths using trigonometric functions
How to elegantly derive the area ratio in terms of x
If you’re preparing for math competitions, studying for school exams, or just love beautiful math, this is the kind of question that sharpens your problem-solving skills and deepens your understanding of trigonometry in geometry.
Animated visuals + clear explanations = a deeper understanding.
