MG 58 – DIAGONALS ON TWO-DIMENSIONAL SHAPES

Children investigate diagonals on convex two-dimensional shapes, including quadrilaterals.
They explain the endpoints of diagonals are the vertices of the shape and identify whether a diagonal is an axis of symmetry.
They measure diagonals, identifying whether they are equal lengths.
Children measure the angle where the diagonals meet, identifying whether they meet at right angles.
