8th Gr Math - Edgenuity Lesson 1 - 4

Congruent segments have the same

• Color
• Texture
• Length
• Weight

Answer explanation

Two figures are congruent if they are exactly the same size and exactly the same shape.

True or False... Two figures are congruent when their corresponding sides and angles have equal measures.

• True
• False

Markings on a figure can be used to show which parts are

• Congruent

• Colored
• Rays

• Related

Answer explanation

Arcs are used to show if angles have the same measurement and hash marks are drawn to show when segments are the same length.

True or False.... Two figures are congruent if they are not the same size and not the same shape.

• True
• False

Match the following

• pre-image

• A geometric shape before a transformation occurs.

• reflection

• A transformation that changes the size but not the shape of a figure.

• image

• A transformation in which every point on a graph is moved over a line so that each point and its corresponding point are equidistant from the line.

• dilation

• The result of a transformation of a geometric shape

True or False... Similar figures are the same shape, but not necessarily the same size.

• True
• False

Match the following

• rotation

• Transformation of a figure in which every point moves the same distance in the same direction

• notation

• Used to label transformed figures.

• translation

• A transformation in which each point on the figure is turned through a given angle and direction around a given point.

• transformation

• An operation on a figure that may change its location in a plane, orientation, or shape.
