If one side of a triangle is double the other, and the angles on opposite sides differ by `60^0,` then the triangle is equilateral (b) obtuse angled (c) right angled (d) acute angled

If one side of a triangle is double the other, and the angles on opposite sides differ by 60^(@) , then the triangle is

If one side of a triangle is double the other, and the angles opposite to these sides differ by 60^(@) , show that the triangle is right-angled.

in one angle of a right triangle is 60^@ ,the other two angle are

If one angle of a triangle is equal to the sum of the other two angles,then the triangle is an isosceles triangle (b) an obtuse triangle an equilateral triangle (d) a right triangle

If the square of one side of a triangle is equal to the sum of the squares of the other two sides then the triangle is a right triangle with the angle opposite the first sides as right angle.

One acute angle of a right angle triangle is double the other. If the length of its hypotenuse is 10 cm, then its area is

If the roots of the equation c^(2)x^(2)- c(a+b)x + ab =0 are sin A, sin B where A, B and C are the angles and a, b, c are the opposite sides of a triangle, then the triangle is : (i) right angled (ii) acute angled (iii) obtuse angled (iv) sin A + cos A = (a+b)/(c )

If the sides of a angled triangle are in A.P then the sines of the acute angles are
