Perpendicular bisector of a line segment
I can use the properties of a rhombus to construct a perpendicular bisector of a line segment.
Perpendicular bisector of a line segment
I can use the properties of a rhombus to construct a perpendicular bisector of a line segment.
Lesson details
Key learning points
- A rhombus can be constructed from two congruent isosceles triangles.
- The diagonals of a rhombus meet at right angles and bisect each other.
- It is possible to construct the perpendicular bisector of a line segment without drawing the rhombus.
Common misconception
I can use a ruler to measure the midpoint of a line segment, and a protractor to find 90°.
Constructions, such as perpendicular bisectors, are methods of creating & modifying shapes & angles in ways that don't require measurements.
Keywords
