Does the black line in the figure represent a line of symmetry?
Yes
No
Explanation
When you are trying to decide if a line represents a line of symmetry you can think about folding the figure across that line. Once you make the fold, do all of the parts line up on top?
If yes, then the line represents a line of symmetry.
If no, then the line does not represent a line of symmetry.
This line represents a line of symmetry because if you fold on the black line, then one side would lay on top of the other and the parts would match up.

The triangle below can be classified as what type of triangle?
Equilateral triangle
Scalene triangle
Isosceles triangle
Right triangle
Explanation
This is an equilateral triangle because the sides are all equal, and an equilateral triangle has to have all sides equal in length.
This triangle is not a scalene triangle because all of the side lengths are not different lengths.
This is not an isosceles triangle because an isosceles triangle has only two equal sides.
This is not a right triangle because a right triangle has to have a right angle, an angle that measures
