2. Prove that such angles are equal.

3. The Hypothesis :
Two angles are in different
planes but each side of one is
parallel to the corresponding
side of the other, and has also
the same direction
The Conclusion :
The angles are equal

4. The students are asking to
draw the figure consider
hypothesis.
And the figure like below :

5. Consider the figure, the
teacher ask “what is the
hypothesis and conclusion ?”

6. Consider the conclusion,
students are asking to think of
a familiar theorem having the
same or a similar conclusion,
“ If two triangles are congruent,
the corresponding angles are
equal.”

7.  Teacher give direction to
student about a pair of
congruent triangles. And
student can make triangles
from the figure 4 :

8. New aim at a conclusion
“Two triangles are congruent
if only if the three sides of
the one are equal
respectively to the three
sides of the other.”
If we knew that BC = B’C’

10. Parallelograms let A to A', B to B', and C to C ‘.
