You have explored the attributes of many different types of triangles. In this module, you will delve deeper into right triangles. You will apply the Pythagorean Theorem to determine a triangles type, and you will also study the attributes of two special right triangles: a 45°-45°-90° and a 30°-60°-90°. In addition, you will begin your study of trigonometry, the branch of mathematics that studies the relationships involving side lengths and angles of a right triangle.
Before you begin your study of right triangles, take a moment to review different types of triangles. In this non-graded interactivity, test your knowledge about acute, right, obtuse, equilateral, isosceles, and scalene triangles. Click the player button to get started.
