B. 2 equal angles

C. All 3 angles of different measures

D. One angle of $$90^\circ$$

List II (Type of triangle)

I. Isosceles triangle

II. Equilateral triangle

III. Right angled triangle

V. Scalene triangle

Choose the correct answer from the options given below.

Solution

A triangle with all three angles equal is equilateral, so A matches II. A triangle with two equal angles is isosceles, so B matches I. A triangle with all angles different is scalene, so C matches IV, and a triangle with one angle of $$90^\circ$$ is right angled, so D matches III. This is option d.
