Study Notes
Diagonals
- A diagonal is a straight line that connects two opposite corners of a polygon.
Types of Diagonals
- There are two types of diagonals in polygons: perpendicular diagonals and mutually bisecting diagonals.
Perpendicular Diagonals
- Perpendicular diagonals cross each other at a right angle (90 degrees).
- A way to remember this is that you could fit the corner of a piece of paper exactly in the right angle.
- Examples of shapes with perpendicular diagonals are kites and squares.
Mutually Bisecting Diagonals
- Mutually bisecting diagonals cross each other at the halfway point of each other.
- Examples of shapes with mutually bisecting diagonals are rectangles and squares.
Drawing Diagonals
- To draw a diagonal, use a straight edge to draw a straight line from one corner to the opposite corner of a polygon.
- By drawing two diagonals, you can determine if they are perpendicular or mutually bisecting.
