Solids in Maths

 Today in maths this is what we made we had to make these shapes out of paper, One is called an octagonal pyramid and the other is a tetragonal star.

These are mine I think I did a good job 

We can determine the solids through the number of faces, edges & vertices.

First one 

Edge-9

Face=16

Vertice=9

Second one 

E=9

F=10

V=9

Defining polygons

 

Today in maths I learnt to define if a shape is a polygon or not.

Polygons have no curves and the sides touch together. They have to be 2D shapes.

A regular polygon has all angles equal and sides equal or its a irregular.

Maths-Lines

This is what we have been doing in maths. We are learning about lines which are horizontal, vertical, parallel, perpendicular which is a right angle(90 degrees) and the lines for 3D shapes at an oblique angle of 45 degrees.
