In a triangle, the perpendicular from the vertex to the base bisects the base. The triangle is (a) right-angled (b) isosceles

Let A (2,-2) B (-2,1) and c (5,2) now , use distance formula , AB = {(2+2)^2 + (-2-1)^2}^1/2= 5 BC ={(5+2)^2 +(2-1)^2}^1/2 = (50)^1/2 CA = {(5-2)^2 +(2 + 2)^2 }^1/2 = 5 now , AB^2...

Let the length of equal sides be x cm. Perimeter = x cm + x cm + Base = 4 2/15 cm 2x + 4/3 = 62/15 On transposing 4/3 to R.H.S, we obtain 2x...

The longest side of a right angled triangle is called its hypotenuse .

It is possible to have a right-angled equilateral triangle. False

(1) (–1, 0) Explanation The centroid of the triangle coincides with the centroid of the triangle formed by joining the middle points of the sides of the triangle. Hence, the coordinates of the...
