**Geometry –Triangles: G 5.a; G 5.1, G 5.b; G 5.4; G 6.1,2,3,4**

2
**To assess prior knowledge: have students make circle maps to define the following:**

Scalene Isoceles Equilateral Obtuse Acute Right Isoceles triangle

3
Congruent Triangles Teacher would have S’s create Circle map to define Congruent triangles. They could then compare the different maps made (gallery walk – by posting on back wall of room) and decide “what must be on every map” for it to define Congruent triangles. A sample map is included. (A Circle map for Similar triangles is also included at end – but intended for a later lesson)

4
**A set of points having the**

Define Ways to Prove Congruent Triangles Identical AAS SSS CPCTC SAS A set of points having the same size and shape SAS 1:1 correspondence of equality AAA – similar but NOT congruent No SSA Examples Non-Example

5
**Practice with Correspondence**

The following multi-flow maps are for practice with identifying triangle parts and correspondence After identifying relationships, (1/2: event - results) then students can pick out the items that cause congruence with rule – (1/2 : results/causes – event=congruence)

6
**Then If If Then <AAS Congruence Sample multi-flow UW = WU**

<UTW = <UVW <UWT = <UWV = 90° <UTV = <UVT ∆TUV Sample multi-flow

7
**Can use cards with figures printed on them for kids to sort. **

This is intended as a “working map” that kids will complete.

8
**Another example of a working map with S’s filling in blanks for a variety of figures**

9
**Corresponding angles =**

Corresponding sides = AAS Congruent ∆ Equal & Tilde SSS Double Bubble – comparison – similarities & differences

10
**Define Ways to Prove Examples Non-Example AAA**

Similar Triangles AAA A set of points having the same shape AAS SSS SAS SAS 1:1 correspondence of Proportionality of sides Examples Non-Example

11
**Rt. Click or Ctrl click to add text**

Flow Map - Sequencing

12
**Multi-flow Map– Cause & effect**

Effects Causes Event Multi-flow Map– Cause & effect

13
**Brace Map – Whole to part; physical separations**

14
RF: as as Bridge Map – for analogies; always put relating factor
