Thursday February 5 HOMEWORK

Assignment: p. 423 in your textbook. Find a counter-example for each of the 3 statements (if possible)

Details:  For each of these statements, you need to try and draw an example that proves it wrong.


Statement 1 - If two triangles have their corresponding angles equal, then the triangles are similar. 
** Try to draw 2 triangles with the same angles as each other, that are NOT the same shape**



Statement 2 - If two triangles are both isosceles, then the triangles are similar. 
** Try to draw 2 isosceles triangles (isosceles means 2 sides are the same length) that are NOT the same shape**



Statement 3 - If two triangles have their corresponding sides proportional, then the triangles are similar. 
**Try to draw 2 triangles with proportional (or same length) sides, that are NOT the same shape**



Hint: you will only be able to get a counter-example for Statement 2, but draw examples for the other statements too.

Due: Tomorrow (Friday) in class
