Question 1 of 3

A vertical line of symmetry is drawn between the third and fourth positions in a row of shapes. The shapes shown to the left of the line, from left to right, are: red square, blue triangle, green circle. Which shape should be placed in the fourth position (the first position to the right of the line) so that the entire row is symmetrical about the line?

Question 2 of 3

A square sits to the right of a vertical mirror line, and a small right‑triangle is attached to the right side of the square. Which description shows the correct reflection of this shape across the mirror line?

Question 3 of 3

An isosceles triangle has a horizontal base and two equal slanted sides that meet at the top point. Which line would be a line of symmetry for this triangle?
