Triangle Properties and Relationships

The video tutorial covers the basics of determining if given pipe lengths can form a triangle using inequalities. It explains the importance of angle and side relationships, including vertex identification. The tutorial emphasizes the use of graph paper for visualizing geometric problems and discusses testing side lengths to determine possible triangles, highlighting the importance of understanding limits and boundaries.

Which of the following sets of pipe lengths can form a triangle?

• 3, 4, 8

• 5, 12, 13

• 2, 2, 5

• 7, 10, 18

If you have sides of lengths 6, 3, and 9, what should you be cautious about?

• The largest side should be equal to the sum of the other two sides.

• The sides should all be equal.

• The sum of the two smaller sides should be greater than the largest side.

• The smallest side should be greater than the difference of the other two sides.

When ordering sides from smallest to largest, which side should be considered first?

• The side with the smallest angle opposite it.

• The side with the largest length.

• The side with the smallest length.

• The side with the largest angle opposite it.

In a triangle, if angle J is the smallest, which angle is likely the largest?

• Angle J

• Angle L

• Angle M

• Angle K

What is the vertex of angle X in a triangle?

• The first letter in the angle name

• The middle letter in the angle name

• The last letter in the angle name

• The letter not in the angle name

What is the significance of the middle letter in an angle's name?

• It represents the largest angle.

• It represents the vertex of the angle.

• It represents the smallest angle.

• It represents the base of the triangle.

What should you do if you have two angles of a triangle?

• Calculate the third angle.

• Draw a perpendicular line.

• Find the longest side.

• Measure the base.

Why is it useful to use graph paper during a test?

• To draw perfect circles

• To visualize and organize geometric problems

• To write down notes

• To calculate arithmetic problems

If AC is the shortest side, which side is the longest?

• CB

• CA

• AB

• BC

What is the relationship between the largest side and the largest angle in a triangle?

• The largest side is unrelated to the largest angle.

• The largest side is opposite the largest angle.

• The largest side is adjacent to the largest angle.

• The largest side is equal to the largest angle.
