19. Time to think…  fd 50  rt 120  fd 50  rt 120  fd 50  rt 120  What type of polygon do these commands form? Equilateral Triangle, Acute Triangle, Isosceles Triangle

20. Time to think… Are these triangles congruent or similar and why?

21. Time to think…  Are these triangles congruent or similar and why? Similar because their angles are the same and their sides are in proportion

22. Time to think…  What type of angle is this?

23. Time to think…  What type of angle is this? Obtuse… more than 90°

24. Time to think… 75 º Find the missing angle: ?

25. Time to think…  The missing angle is 105 º

26. Time to think…  If a triangle has a 40 º angle and a 70º angle, what is the third angle?

27. Time to think…  If a triangle has a 40 º angle and a 70º angle, what is the third angle?  The missing angle is 70º.

28. Explain…  Why is a square a rectangle, but a rectangle not a square?

29. Explain…  Why is a square a rectangle, but a rectangle not a square?  A square is a rectangle because it has two pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.
