Answer 2

Answer:

The correct option is c) A triangle with two equal sides is called a scalene triangle.

Step-by-step explanation:

• An equilateral triangle, which is frequently referred to as a "regular" triangle, is a triangle with three equal-length sides.
• Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle.
• A triangle is said to be right-angled if one of its angles is exactly 90 degrees.
• The longest side, called the hypotenuse, is always in opposition to the right angle.
• The other two sides sum up to 90 degrees and both are acute angle.
• A scalene triangle is a triangle with three different side lengths and three different angle measurements.
• The total of all interior angles, however, is always equal to 180 degrees. As a result, it satisfies the triangle's condition of angle sum.
• An isosceles triangle has two equal sides as well as two equal angles.
• Hence, Option C is a false statement as in scalene triangle, all sides are unequal.
