MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Which type of lines meet at a angle?
curved
diagonal
parallel
perpendicular
Answer explanation
The correct answer is perpendicular. Perpendicular lines intersect at a right angle, or 90 degrees.
Curved lines is incorrect because curved lines don’t meet at an angle; an angle is formed by the intersection of two lines, segments, or rays. Not all diagonal lines intersect. Parallel lines are lines that will never intersect; they will always be the same distance apart from one another.

DRAW QUESTION
3 mins • 2 pts
Draw line segments on the grid to show ALL the lines of symmetry for this polygon.
Answer explanation
A line of symmetry divides a figure into two equal pieces that would fold onto each other. The shape drawn is a rhombus, which can be divided into two equal pieces with a segment through each pair of opposite angles.

DRAW QUESTION
3 mins • 1 pt
Draw a five-sided shape that has 1 line of symmetry by adding 2 line segments to the three sides already drawn on the grid.
Answer explanation
Two possible correct responses are shown below. These responses are correct because the shape in each response has 5 sides and 1 line of symmetry. The 2 sides that are added intersect halfway between the vertical sides that are provided.
