Under construction. 

Isometries: transformations of the plane that preserves length and angle measures. Composition: operation that consists of having one transformation follow another. Composite: single transformation that results from a composition of two transformations. Isometric figures: figures that can be associated by an isometry or that have the same angle measures and lengths of sides. Congruent elements: elements such as angles, sides, medians... that have the same measures. Two congruent elements are isometric. Definition: statements describing the nature of geometric figures in terms of their essential characteristics. Geometric properties: statements of observable facts about geometric figures. Axioms: statements considered to be obvious and accepted as true. Theorems: propositions that have been proved using logical reasoning made up of statements, definitions, properties, axioms or theorems that have already been proved. Converse: proposition in which the hypothesis and conclusion have been interchanged. Counterexample: an example which contradicts a proposition. Corresponding angles: two angles at different vertices, located on either side of the intersecting line, one inside the other two lines and the other outside them. Alternateinterior angles: two angles at different vertices, located on either side of the intersecting line and inside the other two lines. Alternateexterior angles: two angles at different vertices, located on either side of the intersecting line and outside the other two lines. 

Terminal objective  To solve problems using the concept of isometry. Intermediate objectives  To distinguish isometric figures from those that are not.  To describe an isometry involving two polygons.  To support a statement used in presenting a proof involving isometry. Skills  Distinguishing isometric figures from those that are not.  Describing an isometry involving two polygons.  Supporting a statement used in presenting a proof involving isometry.
