## How do you find the perimeter of a SAS triangle?

To find the perimeter of a triangle, use the formula perimeter = a + b + c, where a, b, and c are the lengths of the sides of the triangle. For example, if the length of each side of the triangle is 5, you would just add 5 + 5 + 5 and get 15.

**What is a formula of perimeter of triangle?**

Hence, the formula for the Perimeter of a Triangle when all sides are given is, P= a+b+c. Where, a, b, c indicates the sides of the triangle.

**What is the area and perimeter of isosceles triangle?**

The area of an isosceles triangle is given by the following formula: Area = ½ × base × Height. Also, The perimeter of the isosceles triangle. P = 2a + b.

### How do you find the sides of a triangle with the perimeter?

Perimeter of a Triangle

- In the given triangle, a, b and c are the sides of the triangle. Perimeter of a triangle.
- Perimeter of triangle = a + b + c.
- Here, sides of the triangle are AB = 3 cm, BC = 4 cm and AC = 3 cm.
- Perimeter of an isosceles triangle = a + b + c.
- Perimeter of an equilateral triangle = a + b + c.

**What is the perimeter of this right triangle?**

The perimeter of a right-angled triangle is the total length of its boundary or the sum of the lengths of all three sides, which includes the hypotenuse, the height, and the base. This is calculated with the formula: P = base + height + hypotenuse.

**How do you find the perimeter of a polygon triangle?**

Formula for Perimeter of Polygon Perimeter of a triangle = a + b + c, where, a, b, and c are the length of its sides.

#### How do you find the area and perimeter of an isosceles triangle?

Use a similar formula, Perimeter = 2A + B, to find the perimeter of the isosceles triangle, where A and B are the length of the legs and base. Solve for area just as you would any other triangle using the formula Area = 1/2 B x H, where B is the base and H is the height.
