Q. A triangle has vertices on a coordinate grid at A(3,−6),B(−6,−6), and C(−6,−1). What is the length, in units, of AB ?Answer: □ units
Identify Points A and B: Identify the coordinates of points A and B. Point A is at (3,−6) and point B is at (−6,−6).
Use Distance Formula: Recognize that the length of segment AB can be found using the distance formula, which is derived from the Pythagorean theorem. The distance formula for two points (x1,y1) and (x2,y2) is:(x2−x1)2+(y2−y1)2
Substitute Coordinates: Substitute the coordinates of points A and B into the distance formula.(−6−3)2+(−6−(−6))2
Calculate Differences: Calculate the differences for each coordinate. (−9)2+(0)2
Square and Add: Square the differences and add them together. 81+0
Simplify Square Root: Simplify the square root to find the distance. 81
Calculate Final Value: Calculate the final value of the square root. The square root of 81 is 9.
