### Drawing instructions

**Equilateral triangle**

When you place the triangle tool somewhere on the TactiPad in any orientation and then draw along the inner contour, you create your first equilateral triangle.

**Right corner triangle**

Mark with a dot, or for convenience place a pushpin at the halfway position.

Start to draw a line from here into a corner.

Continue drawing a full side off from the same corner.

Draw a line from the halfway position to the opposite corner.

you have created a 30/60/90 degrees triangle, also known as a 1/2/square root3 triangle.

**Isosceles triangle**

Determine what is going to be the bottom side of the triangle.

Draw a line from the desired corner position on to the halfway position. Continue this line until you reach the position that has the same distance to the halfway position as your starting point has. The starting point is not necessary the corner of the tool.

For convenience you may place pushpins at the corner positions first or after you have created the base line.

Just mark the top corner or place a pushpin in the top corner and provide the lines from the top corner to both base line corners.

**Irregular triangle**

Draw a section of one side, not necessary starting from or ending at a corner of the tool. For convenience you can place pushpins first. Mark or place a pushpin in the desired position along one of the other sides. Provide lines from the marked position to both line endings.

**Diamond with 60 degrees angle**

Place the triangle on the TactiPad. Draw two of the three sides fully. For convenience place a pushpin in one of the corners at the line ending. Lift the tool and rotate it 180 degrees. Place the tool back against the pushpin. Rotate until the free corner matches the line ending. Draw line from here into the corner. Draw the last line, so they connect again in the corner.

Diagonals can be provided by drawing the lines between opposing corners.

**Draw a house**

For the outline of a traditional house use a square and draw three-quarter of the shape. Leave the top side open. To draw the roof, use a triangle, preferably a little larger than the square size. Place this above the walls of the square and draw the inner contour as the top part of the front face.

Use the smaller square tools to add windows.

**Fantasy**

Draw a triangle and place a pushpin in one of the corners. Rotate the triangle in any of both directions and draw again – a part of – the triangle. Repeat this a few times and change the corner to rotate.

**Four equal sided pyramid**

To start, for convenience, use one of the larger sized triangle tools. Orient the bottom side horizontally. Draw the inner contour.

Look for the halfway position on the bottom line. From here, image a line under an angle of 30 degrees and a length of 60% or 70% of the tools side length on this line. Mark this position or place a pushpin there.

Draw a line from the right corner on to this position. Also one line from here to the top of the triangle.

Finally a dashed line from the left corner to the marked position.
