Question

Find the lengths of the sides of the triangle, then click to identify the triangle as scalene, isosceles, or equilateral. R(1, 3), S(3, 1), T(5, 2)

Answer 1

Scalene triangle.
All three segments are different lengths so it is a scalene triangle.
Use the distance formula
`Distance =√((x_2 -x_1)^2 + (y_2- y_1)^2)` to find the distance of the three segments.

`RT=√((1 -5)^2 + (3- 2)^2) =1.4`

`TS=√((3 -5)^2 + (1- 2)^2) =2.2`

`RS=√((1 -3)^2 + (3- 1)^2) =2.8`
