Question

Name the type of triangle formed by the vertices A (5, 4), B(2, 0), C (-2, 3)

Answer 1

Answer:

ISOSCELES RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

AB² = (2 - 5)² + (0 - 4)²

AB² = 25 - (1)

BC² = (-2 - 2)² + (3 - 0)²

BC² = 25 - (2)

AC² = (-2 - 5)² + (3 - 4)²

AC² = 50 - (3)

From (1) , (2) , (3)

AB = BC and AB² + BC² = AC²

SO THE TRIANGLE IS AN ISOSCELES RIGHT ANGLED TRIANGLE.
