What kind of triangle is formed by A(1, 2), B(4, 3) and C(5, 6)?
(a)Equilateral
(b)Isosceles
(c)Right Angle
(d)None of these

The triangle formed by complex numbers z,iz,i^(z)z is (a)Equilateral (b) Isosceles (c)Right angle (d) Scalene

If cos^(2)A+cos^(2)B+cos^(2)C=1, then ABC is (a)equilateral (b) isosceles (c)right angles (d) none of these

The polar coordinates of the vertices of a triangle are (0,0),(3,(pi)/(2))(3,(pi)/(6)). Then the triangle is (b) isosceles (a) right angled (d) none of these (c) equilateral

In triangle ABC, if |[1,1,1], [cot (A/2), cot(B/2), cot(C/2)], [tan(B/2)+tan(C/2), tan(C/2)+ tan(A/2), tan(A/2)+ tan(B/2)]| then the triangle must be (A) Equilateral (B) Isoceless (C) Right Angle (D) none of these

Determine whether the triangle formed by the lines x-7y+12=0,7x+y-16=0 and 3x+4y-4=0 is (a) equilateral (c) isosceles 6. (b) right-angled (d) none

Show that the points A(3, 0), B(6, 4) and C(-1, 3) are the vertices of an isosceles right triangle.

If all the vertices of a triangle have integral coordinates,then the triangle may be (a) right- angle(b) equilateral (c) isosceles(d) none of these

Show that the points A(7, 10), B(-2, 5) and C(3, -4) are the vertices of an isosceles right triangle.

Show that the triangle formed by the points A(1, 3), B(3,-1) and C(-5,-5) is a right angled triangle (by using slopes).

In any triangle ABC if 2cos B=(a)/(c), then the triangle is(A) Right angled (C) Isosceles (B) Equilateral (D) None of these
