Congruence

Getting Ready Partners  A and B Whiteboards

Learning Objective Today we will identify congruent figures.  CFU Key Words  Identify  Congruent  Figures    -

Activating Prior Knowledge

Concept Development Congruence  Figures that are the same shape and size are congruent  If two figures are congruent, then the corresponding parts of the figure have equal measures. CFU A B C D F G H I

Concept Development Checking for congruence - Two ways!  Tracing  Measuring 3cm 4cm 2cm 3cm 4cm 2cm A B

Importance Windows Quilting Building CST!

Skill Development Are ABC and DEF congruent? Figures that are the same shape and size are congruent. If two figures are congruent, then the corresponding parts of the figure have equal measures. Two ways to check:  Tracing  Measuring A B C D EF 60 3”

Skill Development I’m going to think aloud. Are ABCD and EFGH congruent? Figures that are the same shape and size are congruent. If two figures are congruent, then the corresponding parts of the figure have equal measures. Two ways to check:  Tracing  Measuring CFU A B C D E F HG 90 3” 6”

Skill Development Let’s do one together! A B C D E F 90 5cm 12cm 10cm 60 30 60 30

Skill Dev./Guided Practice Just a couple more A B C D E F G H 90 60 30 40 50 A B D CE F 12cm 18cm 3cm 5cm

10cm 4cm 5cm 2cm 60 4cm

Closure Today we identified congruent figures.  Figures that are the same shape and size are congruent  If two figures are congruent, then the corresponding parts of the figure have equal measures.

Closure Which two figures are congruent? A B C D E F G H 3cm 5cm A 60 4cm B

Closure We talked about two ways of checking for congruence?  Tracing  Measuring We also talked about corresponding parts A B C D E F G H 3cm 5cm
