Drawing and Measuring a Triangle

Let's start by drawing the triangle and labeling its vertices:

1. Draw the Triangle: - The vertices of the triangle are given as (0,0), (1,1), and (2,2).

2. Label the Vertices: - Let's label the vertices as A(0,0), B(1,1), and C(2,2).

3. Measure the Lengths of the Sides: - Now, let's measure the lengths of the sides using the distance formula: - Side AB: √((x2 - x1)² + (y2 - y1)²) - Side BC: √((x2 - x1)² + (y2 - y1)²) - Side AC: √((x2 - x1)² + (y2 - y1)²)

4. Calculate the Perimeter: - The perimeter of the triangle is the sum of the lengths of its three sides.

Calculations:

1. Length of Side AB: - AB = √((1 - 0)² + (1 - 0)²) = √(1² + 1²) = √2

2. Length of Side BC: - BC = √((2 - 1)² + (2 - 1)²) = √(1² + 1²) = √2

3. Length of Side AC: - AC = √((2 - 0)² + (2 - 0)²) = √(2² + 2²) = 2√2

4. Perimeter of the Triangle: - Perimeter = AB + BC + AC = √2 + √2 + 2√2 = 2√2 + 2√2 = 4√2

Conclusion:

The lengths of the sides of the triangle are AB = √2, BC = √2, and AC = 2√2. Therefore, the perimeter of the triangle is 4√2.
