What is the perimeter of △ ABC?
To find the perimeter of \triangle ABC we use the Pythagorean Theorem which tells us that |AB|^2 = |AC|^2 + |BC|^2. Since |AC| = 5 and |BC| = 12 we find that |AB| = \sqrt{169} = 13. The perimeter of \triangle ABC is then 5 + 12 + 13 = 30 units.
How do you find the perimeter of a triangle when given vertices?
Perimeter= 3 + 5 + 4 = 12 To find the perimeter of the triangle, find the lengths of each side of the triangle using the distance formula. Use the distance formula to find the length between point A and B, B and C, C and A. Then add all three lengths together to get the perimeter.
How can you find the perimeter of a triangle?
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.
What is the perimeter of a triangle with vertices (- 1 4?
The perimeter is approximately 6.4 units.

How to Find the Perimeter of a Quadrilateral on Graph?
- Step 1: Find the coordinates of the vertices from the graph.
- Step 2: Apply the distance formula to find the side lengths of the quadrilateral.
- Step 3: Add all the side lengths and the sum gives the perimeter of the quadrilateral.
What is triangular area?
The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

What are the sides of triangle ABC?
The three sides for triangle ABC shown above, written symbolically as △ABC, are line segments AB, BC, and AC. A vertex is formed when two sides of a triangle intersect. △ABC has vertices at A, B, and C. An interior angle is formed at each vertex.
