Question

Which type of triangle is formed by the points A (-5, 6), B (-4,-2) and C (7, 5).

Answer 1

To find the type of triangle, first we determine the length of all three sides and see whatever condition of triangle is satisfy by these sides. Now, using distance formula between two points, We see that, AB ≠ BC ≠ CA and not hold the condition of Pythagoras in a ΔABC. i.e., (Hypotenuse)2 =( Base)2 + (Perpendicular)2
