TO start, you gotta find the slopes of each of these coordinates, 1. is perpendicular to another. 2. In the search box at the top, type your coordinates. Your second y coordinate for side3 is wrong: should be y1)). Find the slope of the second and third coordinate: 3. s1 = sqrt((-2 - 3)^2 + (1-11)^2) = sqrt((-5)^2 + (-10)^2) = sqrt(25 + 100) = sqrt(125), s2 = sqrt((-2-7)^2 + (1-9)^2) = sqrt((-9)^2 + (-8)^2) = sqrt(81+64) = sqrt(145), s3 = sqrt((3-7)^2 + (11-9)^2) = sqrt((-4)^2 + 2^2) = sqrt(16 + 4) = sqrt(20). Part of the series: Finding and Using the Area of a Triangle. First use the distance formula to get the lengths of the sides. Types of Triangles Using Coordinates Honors Geometry Pythagorean Theorem 10. Dilating triangle ABC by a factor of 0.5 results in triangle DEF with vertices D (1, 3), E (2, 3), and F (2, 1). Finding the side lengths of triangles can be useful to us if we want to know whether a triangle is isosceles or scalene. Another way you can do this is to check the length of each of the line segments AB, AC, and BC.
