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 This special type of right triangle is similar to theSpecial Triangles The Triangle If you have one side, you can use these formulas (and maybe a little algebra) to get the others The Triangle If you have one side, you can use these formulas (and maybe a little algebra) to get the othersA 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 Is the simpler alternative proof possible using school level Geometry I want to give illustration in class room

Notice that the smallest side (1) is opposite the smallest angle (30°), and the longest side (2) is opposite the largest angle (90°) So while writing the ratio as 1 √3 2 would be more correct, many find the sequence 1 2 √3 easier to remember, especially when it is spoken See also Side /angle relationships of a triangle In the figure above, as you drag the vertices of the triangle to resizeIf you know that it's a triangle and the length of the side across from the smallest angle is 5, then you would be able to determine that the length of the other side is 5√3, or around 86 Then, you could plug these numbers into the equation to find that the area is ½ (5 x 86) = 215Distance formula dx=−()xy−()y 21 2 21 2 Slope of a line m yy xx = − − 21 21 Slopeintercept form of a linear equation ym=xb Pointslope form of a linear equation yy−=mx−x 11 Standard form of a linear equation AxBy=C STAAR GEOMETRY REFERENCE MATERIALS 30 ° 2 x x 60 ° x 3 30° – 60° – 90° triangle x x 45 ° 45

Area of a Triangle The formula to calculate the area of a triangle is = (1/2) × base × height In a rightangled triangle, the height is the perpendicular of the triangle Thus, the formula to calculate the area of a rightangle triangle is = (1/2) × base × perpendicularA right triangle is a special case of a triangle where 1 angle is equal to 90 degrees In the case of a right triangle a 2 b 2 = c 2 This formula is known as the Pythagorean Theorem In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns In this triangle, the shortest leg ($x$) is $√3$, so for the longer leg, $x√3 = √3 * √3 = √9 = 3$ And the hypotenuse is 2 times the shortest leg, or $2√3$) And so on Đang xem Geometry triangle practice The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle

THE 30°60°90° TRIANGLE THERE ARE TWO special triangles in trigonometry One is the 30°60°90° triangle The other is the isosceles right triangle They are special because, with simple geometry, we can know the ratios of their sides Theorem In a 30°60°90° triangle the sides are in the ratio 1 2 We will prove that belowThe 45°45°90° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which the sides corresponding to the angles, 45°45°90°, follow a ratio of 11√ 2 Like the 30°60°90° triangle, knowing one side length allows you to determine the lengths of the other sides The sides of a right triangle lie in the ratio 1√32 The side lengths and angle measurements of a right triangle Credit Public Domain We can see why these relations should hold by plugging in the above values into the Pythagorean theorem a2 b2 = c2 a2 ( a √3) 2 = (2 a) 2 a2 3 a2 = 4 a2
