Triangle Segments and Their Properties

The video tutorial explains different types of line segments within triangles, including perpendicular bisectors, angle bisectors, medians, and altitudes. Each segment type is defined and its properties are discussed. The tutorial also includes a problem-solving section where viewers classify segments in triangles based on their characteristics.

What is the primary focus of the video tutorial?

• Polygon classification

• Properties of quadrilaterals

• Different types of line segments in triangles

• Circle theorems

What is a perpendicular bisector?

• A line that measures the height of a triangle

• A line that starts from a vertex and ends at the opposite side

• A line that is perpendicular to a side and divides it into two equal parts

• A line that divides an angle into two equal parts

Where does a perpendicular bisector typically end?

• At a vertex

• At the centroid

• At the midpoint of the opposite side

• Anywhere on the opposite side

What is an angle bisector?

• A line that measures the base of a triangle

• A line that is perpendicular to a side

• A line that divides a side into two equal parts

• A line that divides an angle into two equal parts

What is the significance of the arcs or hash marks in an angle bisector?

• They indicate the line is perpendicular

• They show the angles are equal

• They mark the midpoint of a side

• They denote the height of the triangle

What is a median in a triangle?

• A line that is perpendicular to a side

• A line that measures the height of a triangle

• A line that divides an angle into two equal parts

• A line that starts from a vertex and divides the opposite side into two equal parts

Does a median always intersect the opposite side at a right angle?

• Only in right triangles

• No, it does not have to

• Yes, always

• Only in isosceles triangles

What is an altitude in a triangle?

• A line that starts from a vertex and divides the opposite side into two equal parts

• A line that measures the base of a triangle

• A line that divides an angle into two equal parts

• A line that is perpendicular to a side and measures the height

How is the area of a triangle calculated using the altitude?

• Base times height

• Half the base times the altitude

• Base plus altitude

• Twice the base times the altitude

In the practice problems, what does segment AD represent?

• An altitude

• An angle bisector

• A median

• A perpendicular bisector
