2D shapes are flat figures like squares, circles, and triangles.

Each shape has specific sides, angles, and properties.

Triangles can be equilateral, isosceles, or scalene.

Quadrilaterals include squares, rectangles, and trapezoids.

Regular polygons have equal sides and angles.

Angle sums vary: triangle = 180°, quadrilateral = 360°.

Perimeter adds the sides; area measures inside space.

2D shape knowledge is vital for design and layout work.

Construction, carpentry, and art rely on shape accuracy.

Identify and sketch these shapes in your surroundings!
