What shape has four equal sides and four right angles?
What is a square?
What is the line that could be drawn on a shape or pattern so that the shape or patter on one side of the line exactly mirrors the other side of the line?
What is line of symmetry?
What do we call a triangle with one angle greater than 90 degrees?
What is an obtuse triangle?
If you look in a mirror, what type of transformation is happening to your image?
What is a reflection?
Name a shape that has three sides.
What is a triangle?
Can a shape be symmetrical if it has no straight lines?
Yes, a circle is an example of a symmetrical shape without straight lines.
What type of triangle has all three sides of different lengths?
What is a scalene triangle?
How does a reflection affect a shape's orientation?
It flips the shape over a line of symmetry.
How many sides does a hexagon have?
What is 6?
How many lines of symmetry does a square have?
What is 4?
Name a triangle with two equal sides.
What is an isosceles triangle?
If a shape is reflected from the left over a vertical line of symmetry, what happens to the shape?
The shape flips over the line of symmetry and ends up on the right side.
What do we call a shape that has no corners and is round?
What is a circle?
Is a triangle always symmetrical? Why or why not?
No, a triangle is not always symmetrical. It depends on the type of triangle (e.g., an isosceles triangle has symmetry while a scalene triangle does not).
What do we call a triangle with all angles less than 90 degrees?
What is an acute triangle?
Can a reflection change the size of a shape?
No, a reflection does not change the size of a shape.
Which 2D shape is known for having opposite sides that are equal and parallel?
What is a parallelogram?
What is the term for a shape that can be folded in half to create two identical halves?
