2. Congruent Triangles

Exercise 41 Page 351

Can you determine the size of a triangle by investigating only its angles?

False

Practice makes perfect

The angles of a triangle tells the shape, but not the size.

If we halve all sides of any triangle, we get a triangle of the same shape (so the angles are congruent), but not the same size (the sides are not congruent). The statement is false. There are noncongruent triangles with three pairs of congruent angles.
