Special right triangle - Wikipedia
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one ...
1.2: Special Right Triangles - Mathematics LibreTexts
Recognize Special Right Triangles. Use the special right triangle rations to solve special right triangles. Hypotenuse equals twice the smallest leg, while the larger leg is 3–√ 3 times the smallest. One of the two special right triangles is called a 30-60-90 triangle, after its three angles.

Special Right Triangles - Formulas, Examples, FAQs - Cuemath
Special right triangles are those right-angled triangles whose interior angles are fixed and whose sides are always in a defined ratio. There are two types of special right triangles, one which has angles that measure 45°, 45°, 90°; and the other which has angles that measure 30°, 60°, 90°.

2023年8月3日 · Special right triangles are right triangles whose angles or sides are in a particular ratio. They have some regular features that make calculations on it much easier. In geometry, the Pythagorean Theorem is commonly used to find the relationship between the sides of a right triangle, given by the equation: a 2 + b 2 = c 2 , where a, b denotes ...
Special Angles in Trigonometry: Secondary O Level Math - Jimmy …
Introduction to Special Trigonometric Angles. Consider the equation: sin30° = 1 2 sin 30° = 1 2. Note that the slightest change in the magnitude of the angle will no longer give an exact sine value. For example, sin 30.0001º = 0.5000015…, and sin 29.9999º = 0.4999984…
