a hexagon
A hexagon and a triangle.
square
First, draw the equilateral triangle ABC, and its altitude AI. Extend the sides AB and AC in such way that the extended parts to be equal in length with the length of these sides. Extend also the altitude AI in such way that the extended part to be twice in length as the altitude length. Label their end points , started from the point C, respectively with D, K, and G. From points D, K, and G, draw the parallel lines to BG, BC, and CD. Label their intersections respectively with E and F. A hexagon is formed, the hexagon BCDEFG, where its sides are equal in length with the length sides of the equilateral triangle ABC.
first draw your baseline, then set your compasses to say twice that length, then draw a circle of the same radius from each end of the baseline, use either intersection as the apex of your isosceles triangle.
An isosceles triangle has a total of 180 degrees, just like any triangle. In an isosceles triangle, two sides are of equal length, which means the angles opposite those sides are also equal. Therefore, if you know the measure of one of the equal angles, you can calculate the third angle by subtracting twice that angle from 180 degrees.
A regular hexagon
A hexagon and a triangle.
a hexagon ( triangle has 3 and a hexagon has 6)
A figure with twice as many sides as a triangle is a hexagon. A triangle has 3 sides, so double that would be 6 sides. A hexagon is a polygon with 6 sides and 6 angles. It is a regular polygon with all sides and angles congruent.
