In this lesson on geometry, we explore key transformations including reflection, rotation, and translation. We'll review essential concepts such as the properties of quadrilaterals, specifically focusing on rhombuses and kites. By understanding definitions, converses, inverses, and contrapositives, we enhance our logical reasoning skills in geometry. Students will engage in hands-on activities to apply these transformations to shapes. Homework is assigned from Chapter 1 to solidify understanding.

If a quadrilateral is a rhombus,then it is a kite. • Converse: (T,F-counterexample) • Inverse: (T,F-counterexample) • Contrapositive: (T,F-counterexample)
If a quadrilateral is a rhombus,then it is a kite. • Converse: If a quadrilateral is a kite,then it is a rhombus. • Inverse: If a quadrilateral is not a rhombus,then it is not a kite. • Contrapositive: If a quadrilateral is not a kite,then it is not a rhombus.
Reflection 1. Measure from the point to the mirror line (must hit the mirror line at a right angle.
2. Measure the same distance again on the other side and place a dot.
Rotation What is another name for “rotate”? How do we rotate a shape?
Translation What is another name for “translate”? How do we translate a shape?
