Which is the Perimeter of an Isosceles Triangle with Equal Sides 8 cm each and Third Side 6 cm?
An isosceles triangle has two equal sides and two equal angles opposite those sides. In this case, the given triangle has two equal sides of 8 cm each and a third side of 6 cm.
Calculating Perimeter:
The perimeter of a closed figure, such as a triangle, is the total length of its boundary. For a triangle, the perimeter is calculated by adding the lengths of all its sides.
To find the perimeter of the isosceles triangle, add the lengths of its three sides: the two equal sides of 8 cm each and the third side of 6 cm.
Perimeter = 8 cm + 8 cm + 6 cm
Perimeter = 22 cm
Therefore, the perimeter of the isosceles triangle with equal sides of 8 cm each and a third side of 6 cm is 22 cm.
Perimeter of Isosceles Triangle
Perimeter refers to the total length of the boundary or outer edge of a closed geometric figure. It is measured in linear units such as centimeters, meters, or inches, depending on the scale of the figure.
Calculating Perimeter of a Shape:
- To find the perimeter of a shape, you add together the lengths of all its sides.
- For simple shapes like squares, rectangles, and triangles, this involves adding the lengths of the individual sides.
Perimeter of Triangles:
- In a triangle, the perimeter is calculated by adding the lengths of its three sides: AB + BC + CA, where AB, BC, and CA represent the lengths of the sides.
- An isosceles triangle has two equal sides and a third side that is different in length.
- To find the perimeter of an isosceles triangle, add the lengths of the two equal sides and the third side together.
Importance of Perimeter:
- Perimeter is important in geometry as it helps determine the total length required to enclose a shape or figure.
- It is also used in real-world applications such as fencing a garden, measuring the boundary of a land plot, or calculating the length of a wire needed for a project.
