What is the third side of a triangle?
The hypotenuse is always opposite the right angle and it is always the longest side of the triangle.
How do you know if its a right triangle?
The definition is very simple and might even seem obvious for those who already know it: a right-angled triangle is a triangle where one and only one of the angles is exactly 90°. The other two angles will clearly be smaller than the right angle because the sum of all angles in a triangle is always 180°.
What is the longest side of a right triangle called?
hypotenuse
Are 8 15 and 17 a Pythagorean triple?
What is a Pythagorean Triple, you ask? It is three numbers that when you add the squares of the two smaller numbers that equals the square of the largest number. And by the way, today is 8/15/17, which is a Pythagorean Triple.
Does 7 24 25 make a right triangle?
Yes, 7, 24, 25 is a Pythagorean Triple and sides of a right triangle. Yes, 9, 40, 41 is a Pythagorean Triple and sides of a right triangle.
Does 15 36 39 form a right triangle?
Example 1: Solve for x. Therefore, the length of the base x of the triangle is approximately 12.1. The Converse of the Pythagorean Theorem states that, if is true, then the given triangle is a right triangle. Hence, the set {15, 36, 39} is a Pythagorean Triple.
What are the side lengths of a 30 60 90?
A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its side lengths are always in the ratio of 1: √3:2. Any triangle of the form 30-60-90 can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions.
What is the 30 60 90 Triangle rule?
Tips for Remembering the 30-60-90 Rules Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).
What are the sides of a 30 60 90 Triangle?
What is a 30-60-90 Triangle? A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.
How do you find the longer leg of a 30 60 90 Triangle?
In any 30-60-90 triangle, you see the following: The shortest leg is across from the 30-degree angle, the length of the hypotenuse is always double the length of the shortest leg, you can find the long leg by multiplying the short leg by the square root of 3.
