- Quiz friday the 22
- Tessiliation project due on monday the 25
- And the test will only occur after hands on fair
After, we corrected our previous homework.
Then we continued with the new lesson:
Similar and Congruent Solids
Congruent solids are two solids in which:
- All corresponding angles are congruent
- All corresponding measurements (edges, apothems, heights...) are congruent
- Area of correspondig faces are congruent
- Volumes are congruent
Similar solids are two solids in which:
- All angles are congruent
- All corresponding measurements (edges, apothems, heights...) are proportional
- Area of corresponding faces are proportional
- Volumes are proportional
When Identifying if two solids are actually congruent, you must compare at least two measurements in order to see if they are proportional:
All measurements should give the same ratio:
All areas should give the same ration:
The volume should be:
And that is all the new subject! The HW is: page 633 # 14-28 all
