Quiz Day

Homework: 23 Radical problems Due Monday September 30

See the Radicals post for help

9/24 Similar Triangle Shortcuts

Objective:

SWBAT determine whether two triangles are similar by analyzing angle measures and side lengths. SWBAT discover shortcuts for triangle similarity for triangles are similar when limited information is given.    The Shortcuts Look at the examples we worked in class.  Homework: 10 Similar triangle problems handout Postulates with Kahn

Radicals 9/23

Objectives: SWBAT simplify radicals   SWBAT multiply, and divide radicals, simplifying when necessary   Simplifying Radicals Steps: Factor into primes Circle your pairs Box the leftovers Rewrite Multiply and Dividing Radicals Rules: Completely simplified (see above) No radicals in the denominator.  Get Radical with Khan :)   Still need more practice? Ask Ms. Davis for more problems :)

Similarity 9/18

 

Objective: SWBAT determine whether two figures are similar by analyzing their angle measures and side lengths.

Remember: We always find the scale factor first.  Then the we use the reciprocal for the similarity ratio. 


Similar Triangles Kahn Video

Dilation 9/17

Objective: CWBAT dilate figures in the coordinate plane from the origin. 
 
A dilation enlarges or reduces all dimensions proportionally. 

• A dilation with a scale factor greater than 1 is and enlargement or expansion. 
• A dilation with scale factor greater than 0 but less and 1 (a fraction) is a reduction or contraction.
