• B. two angles are equal
• C. no angle is equal
• D. one angle =90 o

Answer 1

In an equilateral triangle, all the sides are equal and all the angles are equal.

In an isosceles triangle, two sides are equal. Therefore, the angles opposite to equal sides are equal.

In a scalene triangle, all sides are unequal. Therefore, no angle is equal.

In a right angle triangle, one angle is a right angle.
