#### MG 49 – ANGLE AND SIDE PROPERTIES OF TRIANGLES AND QUADRILATERALS

Children use their developing understanding of measuring and constructing angles with a protractor (Measurement and Geometry 48) to investigate angle and side properties of triangles.

They use a protractor and ruler to measure and construct triangles, identifying the side and angle properties of equilateral triangles, isosceles triangles, and scalene triangles.

They use a protractor and ruler to measure and construct triangles, identifying the side and angle properties of quadrilaterals Including squares, rectangles, rhombuses, kites, and trapeziums.

Children extend their understanding of side and angle properties of triangles and quadrilaterals to enlarge shapes to construct a similar shape – one with the same properties.
