A Proof of why a 30 60 90 Triangle Works Let's take a look at the Pythagorean theorem being applied to a 30 60 90 triangle Remember that the Pythagorean theorem is a 2 b 2 = c 2 Using a short leg length of 1, long leg length of 2, and hypotenuse length of √3, the Pythagorean theorem is applied and gives us 1 2 (√3) 2 = 2 2, 4 = 4 In this video you can learn theorem of 30°60°90° triangle with the help of figure#trianglesstd9th#trianglesclass9#triangletheoremproof#30°60°90°triTriangles Concept A 30 60 90 triangle is a special type of right triangle What is special about 30 60 90 triangles is that the sides of the 30 60 90 triangle always have the same ratio Therefore, if we are given one side we are able to easily find the other sides using the ratio of 12square root of three

30°60°90° triangle Paragraph Proof The Pythagorean Theorem You need to show that a2 b2 equals c2 for the right triangles in the figure at left The area of the entire square is a b 2 or a2 2ab b2 The area of any triangle is 1 2Theorem Application of Pythagoras #short #shortvideo #shortsfeed(b) Since this is a triangle, what should the remaining leg length be?

Theorem of remote interior angles of a triangle Congruence of Triangles Isoscles Triangle Theorem Property of Triangle Theorem Median of a Triangle Perpendicular bisector Theorem Angle bisector theorem Properties of inequalities of sides and angles of a triangle Similar Triangles Working of the Pythagorean theorem A triangle is a unique right triangle that contains interior angles of 30, 60, and also 90 degrees When we identify a triangular to be a 30 60 90 triangular, the values of all angles and also sides can be swiftly determined Imagine reducing an equilateral triangle vertically, right down the middleA theorem in Geometry is well known The theorem states that, in a right triangle, the side opposite to 30 degree angle is half of the hypotenuse I have a proof that uses construction of equilateral triangle

Theorem If the angles of a right triangle are 30, 60 and 90, and if the short side is then the long side is and the other leg is Proof The long side is clearly because of the angles that are twice the size, so we can make an equation t is the other leg We proved it!The ratio of the sides follow the triangle ratio 1 2 √3 1 2 3 Short side (opposite the 30 30 degree angle) = x x Hypotenuse (opposite the 90 90 degree angle) = 2x 2 x Long side (opposite the 60 60 degree angle) = x√3 x 3A triangle is one of the few special right triangles with angles and side ratios that are consistent and predictable Specifically, every triangle has a 30º angle, a 60º angle, and a 90º angle Since these angles stay the same, the ratio between the length of the sides also remains the same

 We can see that this must be a triangle because we can see that this is a right triangle with one given measurement, 30° The unmarked angle must then be 60° Since 18 is the measure opposite the 60° angle, it must be equal to xLesson 51 Pythagorean theorem proof using similarity;For any problem involving a 30°60°90° triangle, the student should not use a table The student should sketch the triangle and place the ratio numbers Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½ Example 2 Evaluate sin 30° Answer sin 30° = ½ You can see that directly in the figure above
