Text: Triangle A(-1,4) B(2,6) C(2,-1) is on the coordinate plane. Calculate the three side lengths, AB, BC, and AC, rounded to the nearest tenth, then classify this triangle as either isosceles, equilateral, or scalene. Show all work.
Added by Elizabeth M.
Step 1
To find the length of side AB, we can use the distance formula. The distance formula is given by: d = sqrt((x2 - x1)^2 + (y2 - y1)^2) Using the coordinates of points A(-1,4) and B(2,6), we can substitute the values into the distance formula: d = sqrt((2 - (-1))^2 Show more…

'Classify the triangle with vertices A(2,1), B(4,5) and C(6,1) as isosceles or equilateral: Use distance formula to justify your answer: Round answers to tenths if needed: Side AB has length side BC has length side AC has length These side lengths support the fact that triangle ABC is'
