Activity 2
Draw One That’s Not . . .
-
Draw a quadrilateral that’s not a square.
-
Draw a quadrilateral that’s not a rhombus.
-
Draw a quadrilateral that’s not a rectangle.
-
Draw as many quadrilaterals as you can that aren’t rhombuses, rectangles, or squares.
Student Section Summary
We learned to sort shapes based on attributes, such as the number of sides, side lengths, and the number of right angles. A right angle in a shape is the angle made by 2 sides that meet like they do in a rectangle. We also sorted quadrilaterals and triangles into more specific groups.
We learned that a shape can be named based on its attributes. For example:
- If a quadrilateral has 4 right angles, then it is a rectangle.
- If a quadrilateral has 4 equal sides, then it is a rhombus.
- If a quadrilateral has 4 equal sides and 4 right angles, then it is a square.
