Time to think…. A park is shaped like a pentagon.
Each side is 41 meters long. What is the perimeter of the park?
Time to think… A park is shaped like a pentagon.
Each side is 41 meters long. What is the perimeter of the park?
205 meters
Time to think… How many lines of symmetry does this
polygon have?
Time to think… How many lines of symmetry does this
polygon have?
Time to think… fd 50 rt 120 fd 50 rt 120 fd 50 rt 120
What type of polygon do these commands form?
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
Time to think…Are these triangles congruent or
similar and why?
Time to think… Are these triangles congruent or
similar and why? Similar because their angles are the same and their sides are in proportion
Time to think… What type of angle is this?
Time to think… What type of angle is this?
Obtuse… more than 90°
Time to think…
75º
Find the missing angle:
?
Time to think…
The missing angle is 105º
Time to think…If a triangle has a 40º angle and
a 70º angle, what is the third angle?
Time to think…If a triangle has a 40º angle and
a 70º angle, what is the third angle?The missing angle is 70º.
Explain… Why is a square a rectangle, but a
rectangle not a square?
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.
Time to think…Solve this riddle: I have two pairs of parallel sides. I have no right angles All of my sides are congruent to each other.
What am I?
Time to think…Solve this riddle: I have two pairs of parallel sides. I have no right angles All of my sides are congruent to each other.
What am I? Rhombus
