A triangle is formed by first plotting a point at (3, 4) on the coordinate plane. The second point is a reflection of the first across the x-axis. The third point is a reflection of the first point across both axes. If the distance between the first point and the third point 10 units, what is the perimeter of the triangle formed?

Answer:
Your answer would be 24 units, as a reflection across the X axis would make the 2nd point be located at (3,-4), putting it at 8 away from the first point. the next would be at (-3,-4), making it be 6 away from the 2nd point. the use the pythagorean theorem to calculate the distance between the first and third point. 8^2+6^2=100, then take the square root of that, which is 10, and you have the distance of the final side. 8+6+10=24
