Equidistance and Angle Theorems

This video tutorial covers perpendicular and angle bisectors, focusing on finding equidistant points using geometric constructions. It explains the perpendicular bisector theorem and its converse, provides a proof, and applies these concepts to solve real-world problems. The angle bisector theorem is also discussed, highlighting its applications in geometry.

What is the perpendicular bisector theorem?

• A line that divides an angle into two equal parts

• A line that is parallel to a segment and bisects it

• A line that is perpendicular to a segment and bisects it

• A line that divides a triangle into two equal areas

In the proof of the perpendicular bisector theorem, what property is used to show that a segment is congruent to itself?

How can Mr. Lee ensure his ice cream cart is equidistant from two park entrances?

• By parking at the entrance of the park

• By parking at the midpoint of the line connecting the entrances

• By parking at the intersection of the perpendicular bisector and Main Street

• By parking at the entrance of the zoo

What does the angle bisector theorem state?

• A point on the angle bisector is equidistant from the sides of the angle

• A point on the angle bisector is equidistant from the vertices of the angle

• A point on the angle bisector is equidistant from the base of the angle

• A point on the angle bisector is equidistant from the midpoint of the angle

If a point is equidistant from the sides of an angle, what can be concluded?

• The point is on the angle bisector

• The point is on the perpendicular bisector

• The point is at the vertex of the angle

• The point is at the midpoint of the angle

What is the relationship between two triangles if they have two congruent angles and a congruent side?
