MATHS Targeted Standards (G) Concept: Geometry (CO) Domain: Congruence Cluster: Understand congruence in terms of rigid motions
MATHS.GCO.06 Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent.
Student Learning Targets:
Knowledge Targets
I can define congruent.
I can define similarity.
I can match corresponding sides in two or more figures.
I can match corresponding angles in two or more figures.
I can identify types of transformations such as translation, rotation, and reflection.
I know that a translation is a slide.
I know that a rotation is a turn.
I know that a reflection is flip.
I can illustrate transformations on a coordinate plane.
I can plot points/ordered pairs on a coordinate plane.
I can use the fact that rigid transformations preserve size and shape to connect the idea and definition of congruence.
Reasoning Targets
I can compare figures to determine if they are congruent.
I can compare figures to determine if they are similar.
I can use a proportion to solve the unknown side or angle of a shape.
I can use a ratio to compare the side lengths or angles of a shape.
I can predict the coordinates of a transformed figure.
I can find the scale factor of two similar figures when given the dimensions.
I can use descriptions of rigid motion and transformed geometric figures to predict the effects rigid motion has on figures in the coordinate plane.
