Ch. 7 Similarity & Congruence Review

Similar is a term used to describe figures or other objects that are similar in size and shape but not identical in terms of dimensions.

True or False, Explain your reasoning.

Congruent refers to figures or anything else that has the same size and shape and can be superimposed on top of each other.

True or False, Explain your reasoning.

What transformation maps the drawing to the actual car

(a)  

Are the views of the drawing of the car silimar to the views of the actual car?

• Yes, the drawing is the same shape of the actual car, but a different size.

• Yes, the drawing is the same color as the actual car.

• No, the drawing is smaller than the actual car.

• Yes, the drawing is the same size as the actual car.

If the scale factor is 1/25, find the following:

b. the distance from the froint wheel to the rear wheel of the actual car.

(a)  

Two figures are (a)   if one can be obtained from other series be series rotations, reflections, or tranlastions.

The parts of congruent figures that match are called (a)  

• similar
• scale factor
• correspomnding parts
• similar polygons

Two figures are (a)   if one can obtained from the other by a series of transformations and dilations.

• similar
