In a triangle, if the middle angle is 18° more than the smallest angle and the largest angle is 18° less than twice the smallest angle, then the three angles are
If the value of an angle is 180°, then the angle is called
Given, ABC is a triangle with side AB = BC = 28 cm and side AC = 18 cm. The triangle is
In an isosceles triangle, two of the sides and two of the angles are equal. If the third angle is 50°, then two equal angles are
For any triangle, SSS stands for
