Geometry Concepts: Angles and Triangles

The video tutorial introduces four key geometry concepts: altitude, median, angle bisector, and perpendicular bisector. Each concept is explained with definitions and examples, highlighting their properties and differences. The tutorial also includes problem-solving exercises to apply these concepts, helping students understand their practical applications in geometry.

What is the primary focus of this lesson?

• Learning about different types of triangles

• Solving algebraic equations

• Exploring the history of geometry

• Understanding four key geometry concepts

What is an altitude in geometry?

• A line parallel to the base

• A perpendicular segment from the vertex to the opposite side

• A segment connecting the vertex to the midpoint

• A line that bisects an angle

Which of the following is true about a median?

• It makes the angles congruent

• It connects the vertex to the midpoint of the opposite side

• It is always perpendicular to the base

• It divides the triangle into two equal areas

What is the primary function of a median in a triangle?

• To create a right angle

• To make angles congruent

• To bisect the opposite side

• To connect the vertex to the midpoint

What does an angle bisector do?

• It makes the sides congruent

• It is perpendicular to the opposite side

• It connects the vertex to the midpoint

• It divides an angle into two equal parts

What is the result when an angle bisector is applied to an angle?

• The angle is divided into two equal parts

• The sides are made congruent

• The triangle is divided into two equal areas

• The opposite side is bisected

What is the result when an angle bisector is applied to an angle?

• The angle is divided into two equal parts

• The opposite side is bisected

• The triangle is divided into two equal areas

• The sides are made congruent

What is unique about a perpendicular bisector?

• It makes the angles congruent

• It always passes through a vertex

• It is perpendicular to a side at the midpoint

• It divides the triangle into two equal areas

Which concept involves a segment that does not necessarily pass through a vertex?

• Perpendicular Bisector

• Altitude

• Angle Bisector

• Median

What type of triangle is formed if a perpendicular bisector passes through a vertex?

• Equilateral

• Isosceles

• Right

• Scalene
