## How would you know that you have proven theorems on kite?

THEOREM: If a quadrilateral is a kite, it has one diagonal that bisects a pair of opposite angles. THEOREM: If a quadrilateral is a kite, it has one diagonal that bisects the other diagonal. THEOREM: If one of the diagonals of a quadrilateral is the perpendicular bisector of the other, the quadrilateral is a kite.

## What does angle bisector theorem prove?

An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle. By the Angle Bisector Theorem, BDDC=ABAC. Proof: Draw ↔BE∥↔AD .

## What is the rule of perpendicular bisector?

A perpendicular bisector can be defined as a line segment which intersects another line perpendicularly and divides it into two equal parts. Two lines are said to be perpendicular to each other when they intersect in such a way that they form 90 degrees with each other.

## What does a perpendicular bisector look like?

Definition: A line which cuts a line segment into two equal parts at 90°. Try this Drag one of the orange dots at A or B and note the the line AB always divides the segment PQ into two equal parts. When it is exactly at right angles to PQ it is called the perpendicular bisector.

## Can you use the perpendicular bisector theorem?

Converse of the Perpendicular Bisector Theorem If a point is equidistant from the endpoints of a line segment, then it is on the perpendicular bisector of the line segment. You can prove or disprove this by dropping a perpendicular line from Point T P o i n t T through line segment HD .

## Does an angle bisector go through the vertex?

Through each vertex draw a line perpendicular to the corresponding angle bisector. These three lines will form a triangle – say ΔA’B’C’.

## What is the difference between a median and a perpendicular bisector?

A median of a triangle is a segment connecting a vertex to the midpoint of its opposite side. A perpendicular bisector splits a segment into two congruent segments and is perpendicular to that segment.
