Example Question #632 : Geometry
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 #633 : Geometry
A triangle has the side lengths , , and . What is the perimeter of the triangle?
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 , or .
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 , or .
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 , or 80 cm.
Example Question #49 : Triangles
The perimeter of an equilateral triangle is mm. Which choice shows the correct side lengths?
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 congruent/equal sides. All the choices add up to mm (except the choice that shows multiplication instead of addition), but only one choice shows equal sides that add up to mm:
Example Question #51 : Triangles
What is the PERIMETER of the triangle in the figure?
30 cm
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 , or .
Example Question #52 : 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 , or .
Example Question #53 : 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 , or cm.
