Example Question #332 : Plane Geometry
If two sides of a triangle measure inches and inches, which of the following is NOT a possible length (in inches) of the third side?
In a triangle, the length of a third side cannot equal or exceed the sum of the other two sides. The sum of the other two sides is equal to . Therefore, the third side cannot be inches or greater. Thus, since is greater than , that cannot be the length of the third side. Thus, is the correct answer.
Example Question #351 : Geometry
The sides of a triangle are equal to inches, foot, and inches. What is the perimeter of the triangle in inches?
The perimeter of a triangle is equal to the sum of its sides.
If the sides of a triangle are equal to inches, foot, and inches, the first step is convert all the sides to inches. This results in:
Therefore, is the correct answer.
Example Question #52 : Triangles
If the perimeter of a triangle is equal to inches, and its sides are equal to , , and , what is the length of the longest side (in inches)?
If the perimeter of a triangle is equal to inches, and its sides are equal to , , and , the following equation can be used to determine the value of :
Divide each side of the equation by .
Given that the longest side of the triangle is equal to , the longest side is . Therefore, is the correct answer.
Example Question #352 : Geometry
In an equilateral triangle, the value of one side is equal to . If the perimeter is equal to 18, what is the value of x?
The perimeter of an equilateral triangle will be 3 multiplied by one side.
Therefore, the following equation would apply:
Applying the distributive property, the following equation results:
Next, we subtract 12 from each side.
Divide both sides by 3.
Example Question #353 : Geometry
If you have a right triangle with a height of 6 inches, a base of 8 inches, and a hypotenuse of 10 inches, what is its perimeter?
If you have a right triangle with a height of 6 inches, a base of 8 inches, and a hypotenuse of 10 inches, what is its perimeter?
Recall that to find perimeter, we simply need to add up the lengths of all the sides.
So our answer must be 24 inches
Example Question #61 : Triangles
An isosceles triangle measures inches along its two equal sides, and inches along its third side. What is the perimeter of the triangle?
To find the perimeter of any shape, simply add the length of each side together. The best answer is:
Example Question #354 : Geometry
An equilateral triangle measures inches along its three equal sides. What is the permiter of the triangle?
To find the perimeter of any object, simply add the length of each side together. The best answer is:
Example Question #355 : Geometry
An equilateral triangle measures inches along its three equal sides. What is the perimeter of the triangle?
To find the perimeter of any object, simply add the length of each side together. The best answer is:
Example Question #61 : Triangles
An isosceles triangle measures inches along its two equal sides, and inches along its third side. What is the perimeter of the triangle?
To find the perimeter of any object, simply add the length of each side together. The best answer is:
Example Question #1293 : Isee Lower Level (Grades 5 6) Mathematics Achievement
An equilateral triangle has a base of . What is the perimeter?
Cannot be determined since you are given one side length only.
An equilateral triangle has three equal sides so the side lengths of this triangle are and .
The perimeter is the total of the three sides so the answer is,
.
