Quadrilateral, pentagon and octagon.
2
Draw a line, a line segment and a ray. Give each a name with capital letters.
Example: line AB (arrows at both ends), segment CD (two endpoints), ray EF (one endpoint E and an arrow).
3
In rectangle PQRS, name the pairs of parallel sides and one pair of perpendicular sides.
PQ and SR are parallel; QR and PS are parallel. PQ and QR are perpendicular.
4
A park is a polygon with sides 12 m, 8 m, 15 m, 9 m and 6 m. Find its perimeter.
12 + 8 + 15 + 9 + 6 = 50 m.
5
