Example Question #41 : Triangles
The perimeter of an isosceles triangle is 22 mm. Which choice shows the correct side lengths of the triangle?
An isosceles triangle has two equal sides, and one different side. All of the answer choices add up to 22 mm, but only one choice shows two equal sides and one different side that add up to 22mm.
Example Question #42 : Triangles
An equilateral triangle is a type of triangle that has sides that are each of the same length. If one of the sides of an equilateral triangle is 
Since an equilateral triangle has three equal sides, the total perimeter of the triangle is 
Example Question #43 : Triangles
A triangle has sides of three different lengths. One of its sides is 
We know two of the lengths of the triangle's sides: 
Example Question #44 : Triangles
What is the perimeter of a triangle with a side length of 
There is no certainty of the type of triangle described in this situation. This can be an equilateral triangle, isosceles triangle, scalene triangle, or a right triangle.
There is not enough information to determine the perimeter since we only have the dimension of one side.
Example Question #632 : Plane Geometry
Find the perimeter of a right isosceles triangle with a hypotenuse of 
Write the Pythagorean Theorem.
In an isosceles triangle, the legs are equal:
Solve for the leg.
The perimeter is the sum of the legs and the hypotenuse.
Example Question #45 : Triangles
A triangle has the side lengths 
The perimeter of a triangle is the sum of the three sides.
Add the lengths together to find the perimeter.
Example Question #46 : Triangles
What is the PERIMETER of the triangle in the figure?
Because the question asks you to find the PERIMETER of the triangle, you are looking to figure out the distance around the outside of the triangle. You find the perimeter of triangles simply by adding the length of the three sides together. So the correct answer here is 
Example Question #47 : Triangles
What is the PERIMETER of the triangle in the figure?
Because the question asks you to find the PERIMETER of the triangle, you are looking to figure out the distance around the outside of the triangle. You find the perimeter of triangles simply by adding the length of the three sides together. So the correct answer here is 
Example Question #48 : Triangles
What is the PERIMETER of the triangle in the figure?
Because the question asks you to find the PERIMETER of the triangle, you are looking to figure out the distance around the outside of the triangle. You find the perimeter of triangles simply by adding the length of the three sides together. Then the correct answer here is 
Example Question #49 : Triangles
The perimeter of an equilateral triangle is 
When finding the perimeter of any triangle, you will need to add all three sides. In this case, it is important to note that this is the perimeter of an equilateral triangle. An equilateral triangle has
