How do you find the third side of a triangle given two sides?
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the longest side is one of the two given sides, then the missing side must be greater than the difference between the two shorter sides. If the missing side is the longest side then the missing side must be less than the sum of the two shorter sides.
What do the side lengths on a right triangle add up to?
There's no general rule or pattern to that. The rule/pattern of the side lengths on a right triangle is: (the square of the length of the shortest side) plus (the square of the length of the medium side) adds up to (the square of the length of the longest side)
What is true about the lengths of the three sides of a triangle?
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.
Can 9 8 17 form a triangle?
NO!!! Reason. The sum of the two shorter sides MUSR be longer than the longest side.
What is side A in triangle ABC rounded to the nearest hundredth if B is 35 and C is 21?
Not enough information has been given to work out side A such as any of its angles upon which the sine rule could have been used to find side A but if the given triangle is a right angle triangle then side A is 28 which conforms to Pythagoras theorem for a right angle triangle.
What is the formula for finding a missing side on a congruent triangle?
It is the same length as the corresponding side on the other triangle.
The two shorter side of a right triangle are known as?
The short sides of a right triangle are the legs.
Find the lengths of the side of the right triangle if the longest side of the triangle is four more than the shortest side and the middle side is two more than the shortest side?
There is no such right triangle. You have defined the relationship between three sides of a triangle that does not have a 90 degree angle. In a right triangle the sum of the squares of the shorter sides equals the square of the longest side and 12 + 22 = 5 ; 42 = 16 it does not equal 5 The angles in a triangle with sides 1, 2, 4 units can be found by applying the cosine rule.
What happens to the shorter side of the isosceles triangle?
Nothing happens; it remains the shortest side forever!
What triangle has two equal sides and one longer one?
An isosceles triangle. It is an isosceles triangle even if the third side is shorter.
What is formula of finding the perimeter of a triangle?
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
What is Pythagoras best remembered for?
Pythagoras is most famous for discovering Pythagoras' Theorem, which is a formula for finding lengths of sides on a right angled triangle. The formula is: a2+b2= c2 where c is the hypotenuse (longest side of the triangle) and a and b are the shorter sides.
Can a triangle have side lengths 1 1 and 2.5?
No. Each side must be shorter than the sum of the other two sides.
How long is the longer side of a golden triangle when the shorter side is 7 inches?
A golden triangle is an isosceles triangle such that bisecting one of the equal angles produces a new triangle that is similar to the original. It can be shown that the original triangle must be 72-72-36 degrees. Using trigonometry, or the similarity, it can be shown that the long sides were (1+Φ) times the shorter, where Φ is the golden ratio. So with the shorter side being 7 inches, the longer were 18.3 inches, approx.
How do you determine the length of a right triange side?
by finding out the hypotenuse of the triangle
What could be the third side of a triangle with side lengths of 4 cm and 6 cm?
The sum of the 2 shorter sides must be greater than the longest side to form a triangle
How do you find the third side of a triangle given two sides?
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the longest side is one of the two given sides, then the missing side must be greater than the difference between the two shorter sides. If the missing side is the longest side then the missing side must be less than the sum of the two shorter sides.
