Special Right Triangles Worksheets
What Are Special Right Triangles? We know that there are equilateral triangles with all equal sides and angles. We have an isosceles triangle with two equal sides and two equal angles, we have scalenes with no equal sides or angles, and right-angled triangles that have one 90° angle and three unequal sides. But what are special right triangles? There are two types of special right triangles; the first one is 30-60-90 triangles and 45-45-90 triangles. The first one is a triangle with 30° and 60° as its acute angles. The sides of these triangles have special proportions. The base is half of the hypotenuse length, and the height is √3/2 times of the hypotenuse length. The type 2 special triangles have 45° acute angles. Here the base and the height are equal, and the hypotenuse is √2 times of that height.

Final answer: Special right triangles involve trigonometric relationships and formulas to calculate the ratios of the sides. Explanation: Special Right Triangles: In a right triangle, the sine, cosine, and tangent of an angle can be defined in terms of the adjacent side, opposite side, or hypotenuse.

Hypotenuse equals twice the smallest leg, while the larger leg is √3 times the smallest. One of the two special right triangles is called a 30-60-90 triangle, after its three angles. 30-60-90 Theorem: If a triangle has angle measures 30, 60 ∘ and 90 ∘, then the sides are in the ratio x: x√3: 2x. The shorter leg is always x, the longer ...

There are two "special triangles" in geometry and trigonometry. They are the 30°-60°-90° right triangle that is half of an equilateral triangle, and the 45°-45°-90° isosceles right triangle that is half a square (cut by the diagonal). The side ratios of these special triangles are relatively easy to remember. It is useful to memorize them. __
There are two types of special right triangles; the first one is 30-60-90 triangles and 45-45-90 triangles. The first one is a triangle with 30° and 60° as its acute angles. The sides of these triangles have special proportions. The base is half of the hypotenuse length, and the height is √3/2 times of the hypotenuse length.

The subject in question pertains to special right triangles and how to apply trigonometry to solve problems involving these figures. In Mathematics, especially in the context of a geometry or trigonometry course at the high school level, special right triangles refer to the 45-45-90 and 30-60-90 triangles, which have set ratios for their sides.
Answer: x=50. y=25. Step-by-step explanation: So for this triangle we can use trig. To find side x (the hypotenuse) we can do sin60 degrees. *remember SOHCAHTOA, so sin is opposite over hypotenuse. sin60degrees=(25 * sqrt of 3)/x. multiply each side by x to get xsin60degrees=25*sqrt of 3. Then divide both sides by sin60degrees.
Perimeter = 64·√2; Length of the ramp = 6.25 feet; Speed = 106.1 feet/s; Method by which the above responses are obtained; 1. An acute angle of the right triangle = 45° Length of the legs are equal; x = 13. y = 2·√13. 2. ∠45° x = y. √2·x = 30. x = 30 ÷ √2 = 15·√2 = y. 3. An acute angle of the right triangle = 60° Therefore ...
