2D and 3D shape

Primary 6B were exploring different types of triangles.

Equilateral Triangles;  all three sides equal, all 3 angles equal and no parallel or perpendicular  lines.

Isosceles Triangles; two sides are equal and two angles are equal.

Right Angle Triangle;  one angle is 90 degrees and  has perpendicular lines.

Scalene Triangle;  all 3 sides and angles are different.

We have also been looking at the nets of 3D shapes.

We made cubes with 6 squares.

We made cuboids with four rectangles and two squares.

We made triangular prisms with three rectangles and two triangles.

We made square based pyramids with one square and four triangles.

We made triangular based pyramids with 4 triangles.

We made regular dodecahedrons  with 12 pentagons.

We made octahedrons with eight triangles.
