Identifying Scalene Triangles and Their Characteristics

The video tutorial by Mr. J explains what a scalene triangle is, emphasizing that none of its sides are of equal length. It discusses how triangles can be classified by their sides or angles, with scalene triangles being classified by their sides. The video provides examples of scalene triangles, illustrating that all sides are different in length. Additionally, it highlights that none of the angles in a scalene triangle are equal. The tutorial concludes with a reminder that if none of the sides are the same length, it is a scalene triangle.

What defines a scalene triangle?

• All sides are of equal length

• At least two sides are of equal length

• All angles are of equal measure

• No sides are of the same length

Which statement is true for scalene triangles?

• They have one angle greater than 90 degrees

• They are always large triangles

• They have two equal sides

• They have sides of different lengths

How can triangles be classified?

• Position and orientation

• Sides and angles

• Color and texture

• Size and shape

What are the side lengths of the first example of a scalene triangle?

• 6 meters, 6 meters, 10 meters

• 6 meters, 10 meters, 8 meters

• 8 meters, 8 meters, 8 meters

• 5 meters, 5 meters, 5 meters

What can be inferred if a triangle has sides with lengths 7 meters, 5 meters, and 9 meters?

• It is an isosceles triangle

• It is an equilateral triangle

• It is a scalene triangle

• It is a right triangle

What do different tick marks on the sides of a triangle indicate?

• All sides are the same length

• Each side is longer than the other

• No two sides are of the same length

• The triangle is equilateral

What does the presence of different numbers of tick marks on a triangle's sides signify?

• It is a right triangle

• It is an equilateral triangle

• It is an isosceles triangle

• It is a scalene triangle

In a scalene triangle, how do the angles compare?

• One angle is 90 degrees

• All angles are equal

• Two angles are equal

• No angles are equal

Are the angles in a scalene triangle ever equal?

• Only in special cases

• No, never

• Yes, always

• Yes, sometimes
