Level 3
The patterns show a sequence of shapes. Each shape has a number of small right-angled triangles. A dot is placed at each point where there is a vertex of one or more right-angled triangles. The total number of dots and the number of small right-angled triangles of each figure is shown in a table.
Find the total number of dots required to form Pattern 4.
Find the total number of dots required to form Pattern 20.
Find the number of small right-angled triangles in Pattern 50.
