Construct An Equilateral Triangle Equilateral triangles are easily constructed with a drawing compass straightedge and pencil because the Math Processing Error interior angles can be found using only the radius of a circle around the triangle a circumscribed circle. These unique features make Virtual Nerd a viable alternative to private tutoring.

Extend this line past the boundaries of your circle.
How to construct a equilateral triangle. Mark the point B on the line. To make sure that the vertical line goes exactly through the middle of the circle place your pencils tip at point O and then align the ruler with the pencil tip. 2 Taking 55 cm as radius and A as centre draw an arc.
This is the largest equilateral triangle that will fit in the circle with each vertextouching the circle. Pick any length for a side of the equilateral triangle. Equilateral triangleinscribed in a circle with a compass and straightedge or ruler.
3 Taking 55 cm as radius and B as centre draw another arc. The ruler will be slightly off-center but the line will not. This is very similar to the construction of an inscribed hexagon except we use every other vertex instead of all six.
Once you click OK a triangle will a appear on your canvas. Stretch the compasses to any width. 1 Draw a line segment AB of length 55 cm.
In this non-linear system users are free to take whatever path through the material best serves their needs. Join AC and BC and label the sides. 4 Let C be the point where the two arcs intersect.
Here 8 cm 40 and 50. Go through the steps below to construct an equilateral triangle. Set the Sides input to 3 and leave the default input for Radius.
This is what to do when you know the length of 1 side and the 2 angles at each end of it. Construct a Triangle You can construct a triangle with Sketchpad by simply drawing three connected segments. The first step is to the grab the Polygon Tool.
It works because the compass width is not changed between drawing each side guaranteeing they are all congruent same length. Put the sharp end of the compasses at point B and draw. It begins with a given line segment which is the length of each side of the desired equilateral triangle.
Use a ruler to draw a line from the end of the line through the dot and label the angle 40. Unlike a triangle that you draw on paper a Sketchpad triangle is dynamicit can moveand can become any triangle at all just by dragging its vertices to change its size and shape. This page shows how to construct an equilateral triangle with compass and straightedge or ruler.
How to construct a triangle given 1 side and 2 angles STEP 1. To make a triangle in Illustrator grab the Polygon Tool and click on your canvas to bring up the polygon settings menu. Use a ruler to draw a vertical line straight through point O.
