Triangle Properties and Classifications

The video tutorial explains how to classify triangles based on their sides. It covers scalene, isosceles, and equilateral triangles, providing definitions and characteristics for each type. Examples are used to illustrate equilateral and isosceles triangles, highlighting congruent sides and their implications in triangle classification.

What is the primary focus when classifying triangles in this tutorial?

• Area of the triangle

• Sides of the triangle

• Color of the triangle

• Angles of the triangle

Which type of triangle has all sides of different lengths?

• Right

• Scalene

• Isosceles

• Equilateral

What is a characteristic of an isosceles triangle?

• All angles are equal

• It has a right angle

• All sides are different

How many congruent sides does an equilateral triangle have?

• Two

• Three

• One

• None

In the example, what indicates that the triangle is equilateral?

• Different side lengths

• Congruent side markings

• Different angles
