19/04/2008 · I have a triangle, with sides 8.5, 6.8, and 9.4, what is the largest angle? I think that it will always be the angle opposite the longest side, and used the cosine rule from there, along with trig identies to find the largest possible angle (<180).... A right triangle is a triangle that has one angle equal to 90 degrees. This is often referred to as a right angle. The standard formula for computing the length of the long side of a right triangle has been in use since the days of the ancient Greeks.

**Using Pythagoras' Theorem How to find the longest side**

Note: The hypotenuse is the longest side in a right triangle, which is different from the long leg. The long leg is the leg opposite the 60-degree angle. The figure illustrates the ratio of the sides for the 30-60-90-degree triangle. A 30-60-90-degree right triangle. If you know one side of a 30-60-90 triangle, you can find the other two by using shortcuts. Here are the three situations you... 9/08/2018 · The hypotenuse is the longest side of the triangle, and it’s also very easy to find using a couple of different methods. This article will teach you how to find the length of the hypotenuse using the Pythagorean theorem when you know the length of the other two sides of the triangle. It will then teach you to recognize the hypotenuse of some special right triangles that often appear on tests

1. An obtuse triangle, XYZ, has two angles acute and one angle obtuse. 2. The perpendicular bisectors of the three sides of XYZ intersect at the circumcenter of the circle. 3. The medians drawn from X, Y and Z intersect at the centroid of the triangle. 4. The circumcenter will always lie outside the how to get codename gordon When using triangles it is possible to work out the length of a side of a triangle or the size of an angle within it if you know some of the other sides or angles. The study of the relationship between the length of sides and the size of angles is called trigonometry .

**How do we know which side of a triangle is it's base**

19/11/2018 · Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. how to get rid of ants outside on patio the perimeter of a triangle is 43ft. The shortest side is one-third of the length of the middle side. The longest side is 3ft more than four times the shortest side. find the lengths of the three sides.

## How To Know What Triangle Side Is Longest

When you're given three side lengths, imagine the two shortest ones put end to end and the longest side placed directly under them. If the two short ones put together are longer than the longest side, they'll be able to angle up to form a triangle.

- We know the area of the triangle. We know two sides of the triangle. The easiest way to find the other side is using the Heron's formula. That's one way.

- Here if the shortest side is 15, then the scale is k=15/5=3, so all sides of the second triangle are 3 times longer than the respective sides of the first triangle. So the simmilar triangle has sides of lengths: 15,18 and 30. Finally we can write answer: The longest side of the second triangle is 30 units long.
