Diagonals to Quadrilaterals II
Students identify the properties of different polygons. For this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.
Curated OER
Translations
Students perform translations on different polygons. In this geometry lesson, students create figures that will be used as an assessment to represent transformation. They perform hands on creation and relate it to the real world.
