Triangle Properties and Construction

The video tutorial covers building polygons, focusing on triangles. It explores possible positions for points in a triangle, the triangle inequality theorem, and constructing triangles with given side lengths. The use of applets for interactive learning is demonstrated, and the lesson concludes with a summary and practice problems.

What is the main focus of the lesson introduced in the video?

• Building polygons and understanding their properties

• Learning about different types of angles

• Studying the properties of circles

• Exploring the history of geometry

If Lynn is three meters away from the slide, what shape does her possible position form?

• A square

• A rectangle

• A triangle

• A circle

What is the range of distances Lynn can be from the swing?

• 1 to 5 feet

• 2 to 8 feet

• 4 to 9 feet

• 3 to 7 feet

What is the minimum length the third side of a triangle can be if the other two sides are 5 and 4 inches?

• 3 inches

• 1 inch

• 2 inches

• 4 inches

What is the maximum length the third side of a triangle can be if the other two sides are 5 and 4 inches?

• 8 inches

• 9 inches

• 10 inches

• 11 inches

What path does a point trace when constructing a triangle with a fixed side length?

• A straight line

• A square

• A circle

• A triangle

When constructing a triangle with sides 3, 3, and 4 units, what is the key factor to consider?

• The height of the triangle

• The length of the base

• The angle between the sides

• The color of the sides

What happens if the sum of the two shorter sides of a triangle is equal to the longest side?

• A square is formed

• A circle is formed

• A triangle is formed

• No triangle is formed

Why is it impossible to form a triangle with side lengths 21, 4, and 2?

• The sum of the two shorter sides is less than the longest side

• The sides are too short

• The sides are too long

• The sides are not integers

What should you be careful about when solving practice problems on Google Classroom?

• Choosing the correct answer

• Using a calculator

• Drawing diagrams

• Timing your responses
