The longest side in a triangle
is opposite the largest angle
, and the shortest side is opposite the smallest angle. Triangle Inequality: In any triangle, the sum of the lengths of any two sides is greater than the length of the third side. Pythagorean Theorem: In a right triangle with hypotenuse . c , a 2 + b 2 = c 2 .
What is the rule for triangle side lengths?
Triangle Inequality Theorem. The
sum of the lengths of any two sides of a triangle is greater than the length of the third side
.
What is the rule for finding the missing side of the triangle?
Answer. Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is
a2+b2=c2 a 2 + b 2 = c 2
, which is known as the Pythagorean Theorem.
What is the rule to make a right triangle?
The Pythagorean theorem states that, in a right triangle,
the square of the length of the hypotenuse (the side across from the right angle) is equal to the sum of the squares of the other two sides
. So if the length of the hypotenuse is c and the lengths of the other two sides are a and b, then c^2 = a^2 + b^2.
How do you find the sides of a triangle from shortest to longest?
Univ.
To put the sides in order of longest to shortest, first find the largest angle —
the longest side is opposite this angle
. Then, find the second largest angle and the side opposite from it to find the next largest angle, and finally, the shortest side will be opposite the smallest angle.
Where would the longest side of a triangle be located?
The longest side in a triangle is
opposite the largest angle
, and the shortest side is opposite the smallest angle.
Which is the longest side in the triangle PQR right angled at P?
Answer. QR is the longest side of the right angled triangle with P at 90 degrees. QR is
the hypotenuse
. Longest side in a right angled triangle is hypotenuse.
How do you find the 3rd side of a triangle?
You can use the
Pythagorean Theorem
to find the length of the hypotenuse of a right triangle if you know the length of the triangle’s other two sides, called the legs. Put another way, if you know the lengths of a and b, you can find c.
Which is the longest side of a right angle triangle?
The hypotenuse
of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle.
How do you find the long side of a right triangle?
- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
- In a right triangle, one of the angles has a value of 90 degrees.
- The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
Where would the largest angle of a triangle be located?
Just like with the sides, the largest angle is
opposite the longest side
.
Where is the largest angle in a triangle?

What are the sides of a triangle?
Every triangle has
three sides and three angles
, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
Which is the longest side in the triangle PQR right angled at P Brainly?
Step-by-step explanation: This is because it is
the hypotenuse
and the hypotenuse is always the longest side. The side opposite to the right angle is always the hypotenuse.
In which case of the following length of side of a triangle is it possible to draw a triangle?
No,
it is not possible to
construct a triangle with lengths of its sides as 4 cm, 3 cm and 7 cm because here we see that sum of the lengths of two sides is equal to third side i.e., 4+3 = 7. As we know that, the sum of any two sides of a triangle is greater than its third side, so given statement is not correct.
Which of the following can be the sides of a right triangle?
Consider the greater side as the hypotenuse and
if the square of the hypotenuse is equal to the sum of the square of the other two sides
then these are the sides of a right-angled triangle. Therefore, the given sides are of the right-angled triangle. The right angle lies opposite to the greater side that is 6.5 cm.
What are the formulas for triangles?
What is the Area of Triangle Formula? The basic formula to find the area of a triangle is,
area of triangle = 1/2 (b × h);
where ‘b’ is the base and ‘h’ is the height of the triangle.
Which is the longest side?
Hint: In a right angle triangle,
hypotenuse
is the longest side. The sum of base and perpendicular is always greater than hypotenuse.
How do you find the third side of a triangle if two sides are known?
Just like the Law of Sines,
the Law of Cosines
works for any triangle, not just right triangles. In particular, the Law of Cosines can be used to find the length of the third side of a triangle when you know the length of two sides and the angle in between. To use the Law of Sines to find a third side: 1.
What is the sum of all 3 sides of a triangle?
The sum of three sides of a triangle is known as
perimeter
. Perimeter of triangle is the total length of boundary of the triangle which is equal to the sum of three side lengths .
What is the name of the longest side in a right triangle and where is this side found?
In geometry,
a hypotenuse
is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
How many sides does a triangle?
| Triangle | Edges and vertices 3 | Schläfli symbol {3} (for equilateral) | Area various methods; see below | Internal angle (degrees) 60° (for equilateral) |
|---|
Is this triangle right angled?
It is possible to determine if a triangle contains a right angle using Pythagoras’ theorem .
If the squares of the two shorter sides add up to
the square of the hypotenuse, the triangle contains a right angle.
Which is the longest side in the triangle ABC right angled at B?
The hypotenuse is the longest side in a triangle. So when the right angle is at B, the Longest side would be
AC
.
