Given A(-3, -6), B(3,2), C(7,-1), how do you prove that ABC is a right triangle and not isosceles?
2 Answers
First of all you need to find the length of the three sides AB,BC,AC.
Explanation:
You can find the length of the sides using distance formula.
After calculating the length of the sides check if length of any two sides is equal or not.If it is equal, the triangle is isosceles otherwise not.
Same way you can check if the triangle is right angles or not.
Put the values of the sides in Pythagoras theorem [
Now you can check whether the triangle is isosceles or right-angled.

From above length of sides of triangle it is observed that
of a right triangle.
perpendicular sides.
are equal in length, the triangle is not isosceles. [Ans]
